I totally get you, I'm the same with auto mechanics, I tried but no joy. But I do know a thing or two about cooking.

There are some things you can do to help yourself, get a list together of meats that are better with lengthy time cooking methods- for instance pork shoulder or sirloin.

Get a crock pot, slow cooker, or smoker.

Basically, you can get recipes for these which are literally the same: Season meat, add potatoes, carrots or other hearty vegetables. Set to cook and walk away- it cooks itself.

Cooking at home doesn't always mean cooking from scratch, you can absolutely grab a can of soup (cream of mushroom) and add it to boiled pasta with some canned tuna, then bake it with a little cheese over the top.

Focus on methods & repetitive dishes, then you can branch out from there.

Meats (braise, slow cooked)

Sides (potatoes, root veg, onions)

Seasonings (seasoning blends, packets, etc)

Sauces (bbq, salad dressings, soups, etc)

Don't be too hard on yourself, I am in the kitchen everyday and there is nothing better than a good sandwich for me at home. Simple, easy, not complicated flavors and filling. When we get busier the sandwiches get simpler, lol.

Good luck.
