We recently featured a product I came across called Amazing Grass Kidz Superfood and I got tons of emails from parents afterwards asking for recipes using it. Kenya (frighteningly) loves to eat the powder on its own (something I wouldn't recommend because of the mess -- but it is delicious and nutritious)! I love making smoothies like this Frozen Chocolate Berry one with Kenya because it gets him involved in the cooking process. He loves peeling the bananas, pouring the chocolate powder into the blender and then switching the “on” button to whiz it up.
Getting your kids involved in cooking, in my opinion, is the the most fun and reliable way to get them to eat all of the yummy creations you prepare!
