I made this recipe for the first time today (thanks JOEBunny). My son is napping so he has yet to try them, I tasted one and it was good! I'll update if my son eats them. I didn't have peas or carrots so I put broccoli, carrots and corn in the blender.
Update: My son was OK with the biscuit. He didn't tear into them the way he does the spinach balls but he did eat a half of one. I think the broccoli is too over powering, it takes away from the sweetness of the banana. I think sticking to milder veggie like carrots, corn and peas would work best.
I use about a 1/2 cup of reduced fat bisquick or TJ's whole wheat baking mix, 2 eggs, a banana, then stir in peas and or carrots. Should be about the texture of a chocolate chip cookie, if not add more veggies or more mix to thicken. I drop like a cookie on a cookie sheet and Bake on 400 until done. He can pick them up to eat them and they have everything he needs. Sort of a full meal biscuit. I make a lot at a time and freeze. You can also put peanut butter in them for extra protein.
