Trust me, I know what it is to not like cooking! At all!
So let's not start cooking right away (or more than what you are doing now).
It could be an ultimate goal, but I'm meeting you where you are at.
Something you can do now, is to make some * slightly better choices * next time you eat, or when you shop. Sometimes, it's easy, sometimes you'll have to think a bit more.
Let me give you examples from your list.
- Chef boyardi pasta / chunky soup — Perfect, have you Boyardee, but can you add a little salad on the side? All you need is lettuce + cucumber, and just enough of your favorite vinaigrette. It's OK to not have a big, full of veggies salad. We just want a little better for now. Or chopped tomatoes + chopped cucumber + vinaigre balsamic, in a bowl. Requires a knife and 3 minutes.
- canned soup, canned food — can you try to choose a slightly healthier one, rather than the chunky / full of salts one, something from Le Menu Bleu for instance : https://www.maxi.ca/fr/soupe-pr-te-servir-la-courge-musqu-e-et-ail/p/21545445_EA?source=nspt
- Occasionally regular steak — steak is awesome! What do you eat with it? I found microwavable white rice at Dollarama, without additive and such, a nice portion for 1,25$. Cheap and healthy. (Ou chez Maxi, tu peux trouver le riz blanc basmati de Ben's Original, la liste d'ingrédients est courte comparé aux riz de la même marque avec saveurs, donc le blanc est un meilleur choix: https://www.maxi.ca/fr/bistro-express-plat-d-accompagnement-de-riz-basmat/p/21405476_EA.) To add veggies to your plate, you can chopp a cucumber and it eat as is, or with vinegar, or salt and pepper. Maybe put green beans in boiling water, they will cook in 5 minutes. If you know how to steam them, it's a bit better. Those vegetables don't require much effort to be prepared.
- Pizza ocasionally — pizza is good! The frozen one? One thing you can do it adding vegetables to it, why not chop a red bell pepper and add it to your pizza before putting it in the oven? Yes, it's a thing you can do! You can add frozen brocoli too, or frozen peas.
- "Steak haché" either in tacos or as hamburger — Add a ton of lettuce to it! And instead of pickles in your hamburger, can you add fresh sliced cucumber? Or put both! See, a slight change that is a bit healthier. (If you don't want to add veggies in it, eat them as a small salad on the side. You can do this with pretty much anything.)
- hamburger — rather than the white buns, why not choose a better bread. Can you try this kind of bread? C'est un pain plat, blé entier si tu veux, plus bourratif que le pain blanc à hamburger régulier : https://www.maxi.ca/fr/pains-minces-blanc-grains-entiers/p/20317755_EA?source=nspt
- Chicken Wraps (just not every day) — can you choose a whole wheat tortilla, rather than the white one? Same thing if you do a sandwich, you can choose a whole weat bread, rather than the withe one.
- Chicken breast or "sliced" to cook — This is good! Cook your chicken breast in a aluminium foil in the oven (en papillotte, with any seasonning you like https://www.maxi.ca/fr/poulet-de-montr-al-assaisonnement/p/20321740002_EA?source=nspt), this won't require oil. 20 minutes à 400-425. Choose a fun side to eat with it, something that will fill you enough.
- You can also buy a rotisserie chicken, they cook and sell them warm in pretty much any grocery store. It's cheaper, tastier and you'll have plenty for sandwiches too (you have to debone it, though) : https://www.walmart.ca/en/ip/your-fresh-market-barbecue-roasted-seasoned-chicken/6000195377106
- For frozen meals, I would say add a side to it, a fresh veggie, a fresh fruit after your meal. Or before. It will fill you a little bit. Les Jonathan Garnier, je ne connaissais pas, ça n'a pas l'air si mal!
- Mini carottes + trempette humus, ou trempette de ton choix. C'est mon go-to quand j'ai une fringale! Ou une pomme tranchée + tranches de fromage.
(Un autre exemple : si tu manges du yogourt. Plutôt que de prendre un yogourt avec saveur (et sucré), tu peux prendre le nature et ajouter à la maison un peu de sirop d'érable. Tu contrôles ta quantité de sucre. Si tu aimes par exemple le yogourt à la vanille, plutôt que prendre un yogourt normal, tu peux prendre un grec, qui fournira plus de protéines, ça rempli plus.)
Tu comprends ce que je veux dire par "choisir un petit peu mieux"? Ça ne changera pas nécessairement ta façon de te nourrir, c'est un long processus, mais c'est un début qui ouvrira tes horizons. Et chacun des "un petit peu meilleur choix" que tu vas faire va t'amener à manger un peu mieux, toujours un petit peux mieux. C'est le but, non?
