What kind of dishes and utensils should I get?

Long story short, I got into a heated argument a few days ago with my mom. She then boycotted cooking meals for me permanently, although that remains to be seen. I can't afford to eat out fast food everyday with what little I have, and also since I have no income. I'm currently trying to get into the skilled trades and I will go to the food bank, but until then, I'm gonna buy and eat grocery stuff.

Until my mom is in a better mood, I won't bother asking if she'll still let me use the kitchen, provided I buy my own food and clean up after myself. So far, I only bought 1 loaf of whole wheat bread, 2 small cans of sliced mushrooms, 2 medium cans of tuna, 2 large cans of beans, and 1 jar of peanut butter. It costed me total of around 16.50 bucks after taxes at Walmart, and I did have to resort to cheaper brands.

I definitely need to get a can opener and a plate, but not sure if I need anything else. I do remember my parents giving me some of their dishes, pots, pans, and utensils for when I was in university. But I checked the basement and couldn't find it at all so I think I might have to buy those. I won't be cooking anything until my mom isn't as mad at me and lets me use the kitchen.
