Evenly divide each ingredient into 4 (1/2 pint size) canning jars. Add ingredients in this order: 1/4 cup salsa, 1/4 heaping cup black beans, 1/4 cup cheese, and 2 tablespoons yogurt or sour cream.
Refrigerate for up to two days. Eat straight from the jar or add to a whole wheat wrap.
TIP: Try adding 1/4 cup cooked quinoa or brown rice to each jar.
