Omelet. Eggs are cheap and cook fast, you can put whatever you want in it - prechop/cook things to throw into it. If you're keeping it low-carb, lots of cheese and a spoonful of salsa on top is delicious. If you're eating the same cheap things everyday, then a one-a-day style multivitamin is cheap insurance against deficiency. You'll pee most of it out but it's better than risking an actual deficiency in something.
