You could hire someone to stop by once a week and put a crock pot of food on, and send her on her way. You could buy one of those very large crock pot's. You can make so many things in them. You can put a stew in there, or a pot of beans, or a roast. Heck even someone who don't know how to cook such as yourself can easily watch a YouTube video and drop a roast and some diced potatoes into one easy peasy. Then boom, you have food to last you nearly all week. You can eat several meals. Put it in the fridge and just microwave it when you want some.
If you had the instant pot you could make a batch of rice in one, refrigerate the rice. Then make a roast next and that would take your meals to the next level. I mean to make a roast all you have to do is sprinkle some garlic salt on it add a 1/4 cup of water and put the lid on Boom. Same goes for a chicken, salt it add some butter, close the lid and bam it will cook it's self. The crock pot is perfect for a person who doesn't know how or like to cook.
