These are one of my favorite snacks and picky Turbokid decided they were one of his, too. I couldn't even get him to put the bowl down long enough for me to take a picture, so he's my hand model here.
1 can chickpeas, drained and rinsed
1 Tbsp olive oil
1 Tbsp nutritional yeast
1/4 tsp chili powder
1/4 tsp salt
Preheat oven to 400F. Mix all ingredients together in a bowl. Spread chickpeas into a single layer on a cookie sheet. Bake for 15 minutes, stir, then bake for another 15 minutes.
