There are actually lots of great ready made meals in the stores now. Costco has a Korean Beef that we love, we just have to made some rice. There are some great fresh ravioli that just takes a jar of marinara sauce and some garlic bread. Sam's has my favorite frozen pre-cooked wings, a bag of coleslaw and it is a good meal. Costco General or orange chicken with a carton of fried rice is another easy meal. Well, you get the idea.
For desserts, mug cakes are good and super easy. I also like baking the Krusteaz triple chocolate cookies.
