Hi Adriana,
I have a great idea ... just started using it myself. Try cutting a squash (green, yellow, whatever you like) lengthwise, and then again, into finger-sized wedges/sticks. Use an eggwash, then bread them. I usually mix a little salt, pepper, and grated parmesan cheese in with the breadcrumbs (my son loves the extra flavor). Then bake the sticks at 350 degrees until brown and soft. Once they're cooled, kids can even just sit in front of the TV watching Barney having a nutitional snack. This would even work with eggplant, which I've found my son also likes. And the best part? My hubby and I love 'em too! Plus, if a child has an intolerance to dairy, you can adjust the recipe--just brush the sticks with a little olive oil instead of using an eggwash.
Also, try making graham cracker sandwiches. I break the cracker in half, spread on a little peanut butter (homeade peanut butter is good if you have the time--yeah right!! LOL )and mashed banana, and freeze in little baggies. When baby wants a snack, I just pull one out of the freezer, and he munches away. Also a really great treat for teething babies--the cold helps soothe the gums. Of course, these don't have to be frozen first. And, again, if there's a peanut allergy or fear of one, just spread on something else, or just use the mashed fruits! Yummy, yum! Again, the best part? My hubby and I like 'em too :-D
Good luck! I can't wait to read the other suggestions myself! Can never have too many ideas!
