Spicy Chilli Bean Burgers

Place cereal in resealable food-storage plastic bag; seal bag and crush with rolling pin or meat mallet.

In medium bowl, mash beans with fork until no whole beans remain. Add cereal, oats, onions and egg; mix well. Shape mixture into 5 patties, each about 3 1/2 inches in diameter.

Spray 12-inch skillet with cooking spray. Add patties; cook over medium heat about 10 minutes, turning once, until brown.

For each sandwich, place 1/4 cup spinach leaves and 1 tomato slice on bottom half of bun; top with bean burger and top half of bun.
