Okay, nothing wrong with that. I'm about to go to bed but can throw some recipes at you and just some general guidelines to work with like being efficient with your food and having a few meals that share ingredients. Pastas are an easy start, pizzas are easy af aside from dough but you can make a solid pizza out of grocery store naan or even pita bread. Any Flatbread thicker than a tortilla really. Burritos are also a huge one. If you have some jars and fridge space pickling is fun as hell and easy. Bowl of stuff with rice or potatoes depending on the stuff is also a good fridge cleaner.

My main overall advice is don't be intimidated cooking wise. Unless you're baking recipes are guidelines and even though it probably won't be just right the first time, it's pretty hard to make food you like with ingredients you like that you won't find at least okay and by tasting you'll have a general idea of what to fix the next time you make that dish and you repeat that over a bunch of meals and you'll be fine. I'll give some easy options that have shared ingredients and some ways to make em a bit nicer. Spices are your friend big time.
