I love cute themed snacks and think it is a great way to get kids interested in eating healthier. You eat with your eyes first, so presentation is important! Here are a few ideas I found on pinterest.
Flower Bouquet with assorted fruits, veggies, and meat
Grapes and goldfish butterflies
Cheese, grapes, and celery sunflower
Banana, raisin, apple, and pretzel butterfly
Ladybug Brochette with cherry tomatoes, olives, and baby spinach
Easter Bunny made from cottage cheese, egg, raisins, banana, almond, and cheese
Flower Pot Carrots, Parsley, and Dip (would work well with broccoli too)
