This one is my favorite (and I'm not a food photographer, people, so forgive me my rudimentary skills).
1 Banana (peeled, halved lengthwise)
1 TBSP reduced fat peanut butter
1/2 cup lowfat Boston Cream Pie yogurt
2 TBSP Grape Nuts
Place the banana halves in a bowl with cut sides facing inward. Spread the peanut butter on the open banana. Spoon the yogurt in the middle. Top with Grape Nuts.
