Tupperware is essential for the person who lives alone. A crockpot is also nice for giving yourself the illusion that you are coming home to a wonderful meal that has been cooked for you

A microwave oven goes without saying.
I like chili. I use very lean hamburger, browned, drained, add olive oil, green peppers, Chipotle peppers (ripe, smoked red jalapenos) onion, cumin, a little garlic, a little sugar, chili powder, tomato paste, tomato puree, diced tomatoes, a few canned whole tomatoes, dark red kidney beans. I salt it at the table. I don't make it real hot to taste, but it's spicy. After cooking and cooling, it goes into tupperware and in the fridge. Very easy to make for a quick lunch with soda crackers.
But you can't eat chili all week. So I will grill hamburgers, ribs, chicken and a big pile of grilled veggies (tomatoes, onions, green peppers, yellow squash etc on a weekend and put those in tupperware too.
In the crockpot I like country pork ribs, kraut, cabbage, potatoes. And all kinds of beef cuts. Those leftovers go into tupperware too.
And every now and then I order a pizza - mushrooms, pepperoni, or a Calzone, with riccota, mozarella, mushrooms, pepperoni, fresh garlic.
Another favorite is old fashioned oats. I bring the water to a boil, put the rough cut oats into the pan and take it off the heat and cover for 5 minutes and eat. It comes out al dente. I salt it just a little. Throw the leftover oats away, or mix with raw oats and menhaden oil to use for chum if you go yellowtailing.
PS - Storch, thanks for illuminating about Mojo sauce. I've been wondering what that is for some time. Do you know if it relates to sayings like "get your mojo on" or the way Austin Powers used the word when he lost his "mojo" ?
