1. Bring beans, salsa, garlic, and 1 tsp. cumin to a simmer in saucepan. Reduce heat to medium low, and cook 5 to 6 minutes, or until soft. Remove from heat, and mash with fork to crush beans for creamier filling, if desired.

2. Heat skillet over medium-high heat, and coat with olive oil cooking spray. Wrap corn in paper towels, and squeeze out excess water. Add corn to skillet in single layer, and sprinkle with remaining 1 1/2 tsp. cumin, black pepper, and cayenne pepper to taste. Cook 5 to 10 minutes, or until golden and crispy, stirring frequently.

3. Preheat oven or toaster oven to 350°F. Toast tortillas in toaster oven 1 minute to soften. Alternately, bake tortillas on taco baking rack in oven 7 to 10 minutes, or until crisp. Fill each tortilla with 1/4 cup beans, 1/4 cup corn, 3 spinach leaves, red pepper strips, cilantro, and green onions. Top each taco with 1 Tbs. cheese, if using. Serve immediately, or pack into lunch container, and chill.
