snack on raw veggies, like baby carrots and celery; use baby lettuce to make salads, put some tuna on them if you like that; buy better bread~! frozen is better than canned or packaged, usually.
learn to read the label~! if you can't pronounce it, don't eat it. learn to use the oven to make meat and potatoes, mac n cheese, macaroni and tuna, or salmon, or even chicken (use the macaronis made with vegetables, they taste just the same).
google "beginner recipes" (repeat after me: NO MORE TAKEOUT )

use canned or boxed (NOT cubes) broth to make soup; add all the veggies you like and left-over meat. refrigerate canned veggies and eat cold for snacks.
