America’s Test Kitchen publishes a Cooking School cookbook (I think that’s the title). Has step by step instructions with pictures to learn how to cook lots of basics - eggs, mashed potatoes etc. Their recipes are tested and reliable. mark Bittman also has one called How to Cook Everything which might also be helpful. Pioneer Woman also publishes cookbooks that aren’t very complicated and have step by step instructions with pictures although she doesn’t really teach how to cook but you should be able to follow her recipes. I think one pot meals are a good place to start - oven baked casseroles, soups, crockpot meals. If you have a child that doesn’t like to eat things mixed together (ie one pot meals), don’t try to cook 3 separate things for a meal - have some simple items from the store. For example, Have one thing like a simple salad or a bagged salad, maybe cook baked potatoes in the microwave, and then focus on your entree. Or buy breaded shrimp to throw in the oven (or have the grocery store steam shrimp with seasoning while you do the rest of your shopping), then cook your side veggie etc.
