You need an Instapot and convection toaster oven (basically a more capable air fryer), you're welcome. Throw stuff in a pot/on a metal sheet hit a button and you're done. I spent way too many years without making my own food. Also a new nonstick pan to easily make omelettes with any ingredients you have left over.
If you are super intimidated to start cooking in an Instapot, it's fine to get meal kits like this.
Literally dump it all in with a slow-cooker spices packet and 6 hours later you have days of food. Then start adding more of stuff you like such as extra onions or potatoes.
