Here are some of my favorites:
1/2 cup fat free cottage cheese = 1/2 cup pineapple chunks. Only 150 calories and super delicious! (If you like cottage cheese)
I'm also a big fan of organic peanut butter, put it on a good grainy bread, it's very filling.
I'm a big fan of frozen because my fresh stuff never stays that way. So I like to get frozen chicken breasts or fish fillets and different kinds of veggies and just pair one meat and one veggie.
Veggie burger + spinach salad
For breakfast I like to have a bowl of Kashi with a peice of fruit
And for a refreshing summer snack, I like to get a few kinds of frozed fruit, throw em in the blender, then pour the mix into those little plastic popsicle makers for all-fruit popsicles
