Hi A.,
What a nice Mom you are to think of such good healthy snacks! Some more ideas for you...
Celery with cream cheese, ricotta cheese, or a thick yogurt spread on it; you can put fruit or raisins on top,or something salty like bacon bits or olives if the cheese or yogurt is not sweetened.
Hard-boiled eggs, or egg salad on bread or crackers. If you get diferent kinds of crackers it won't seem like you are repeating stuff
My 14 yo sometimes microwaves a couple of those frozen chicken breast tenders for a snack. He puts a little seasoned salt or garlic salt (or a mix of both) on them while they are cooking--loves them!
Bananas with (or without) peanut butter (or other nut butter--sunflower seed butter tastes great, I think you can get it at Trader Joe's).
Toast (with or without toppings like PB & honey, jelly, cinnamon etc).
Popcorn. You can sprinkle with parmesan cheese or different seasonings if you want.
Any fruit, plain or with a yogurt dip. Or, melt some chocolate chips and dip fruit in that--not a choice for every day, of course, but once in a while.
A cup or bowl of soup, either homemade or from a can.
When they're in season--raw peas, straight from the pod. Yummy!
In colder weather you can microwave apple, peach, or pear slices with a little water, raisins (if desired), cinnamon or other spices (I like curry but it is kind of an acquired taste). I really like adding a little brown sugar and butter/margarine, but if she'll eat it without, that's better for her.
Cereal or oatmeal. Frozen waffles.
Leftover salad (for awhile this was a favorite of my now 14 yo).
Make sure she has some water or other healthy drink. sometimes we think we are hungry when we really are thirsty.
Hope that helps!
