No, seriously.

Pasta pizza

leftover pasta in marinara
pita bread
mozzarella cheese
herbs if you want them

Put a layer of leftover pasta onto a piece of pita bread. If you're feeling extra classy, rub some olive oil on the pita first. Add shredded mozzarella and a couple pinches of any herbs or spices you want: oregano, for instance. Put the whole business in the toaster (or regular) oven and toast or bake until the cheese is melty and the pita is crispy. Then cut the business in fourths.

Eat as is, or retain some semblance of nutrition by putting a handful of salad greens on top of each piece.

You guys, it was awesome. If you ever want to drown in a sea of carbohydrates, this is how you should do it. Be prepared to loll on the couch uncontrollably.
