Mac n' heese isn't healthy, but sometimes you just need something quick. So I like to make a box of shell Mac with peas and tuna--a veggie and protein at least. The key is the shell pasta because the peas fit so cute in them and reminds me of turtles (I also call this Half-shell Hero Pasta...like the ninja turtles).
1 Box Mac n' Cheese Shells (or shell pasta and melt your own cheese)
1 c. frozen peas
1 can tuna, drained (or sliced cooked hotdog)
Cook the pasta; reserve drained liquid to add the peas into for 3 minutes, to cook.
Add cheese to pasta as directed (or do it homemade style).
Then add cooked peas and tuna.
Convenience food...not the best, but healthier than just a box of mac'.
