My favourite easy meal is boil some pasta while you make a white sauce ( you can use a packet or melt butter add flour and milk and stir till boiling) heat frozen veggies in microwave. Mix it all together with a tin of tuna add shredded cheese to each serve and zap in the microwave until melted. It takes 10- 15 min and it can be frozen. Otherwise sausage sandwiches are a favourite too. I make big batches of spaghetti bolognase and freeze them for later.
