Preheat oven to 400 degrees F. Brush both sides of each tortilla with oil; place on an ungreased baking sheet. Bake about 10 minutes or until crisp, turning once.

Meanwhile, coat an unheated medium nonstick skillet with nonstick cooking spray. Preheat skillet over medium heat. Add sweet pepper, green onion, and, if desired, chile pepper. Cook about 5 minutes or until nearly crisp-tender, stirring occasionally. Add the water; cover and cook for 2 minutes more. Spread each tortilla with about 1 tablespoon of the green salsa. Top with cooked vegetable mixture and shrimp. Sprinkle with cheese. Bake about 3 minutes or until cheese is melted and shrimp is heated through. Sprinkle with cilantro. Makes 2 servings.

Because chile peppers contain volatile oils that can burn your skin and eyes, avoid direct contact with them as much as possible. When working with chile peppers, wear plastic or rubber gloves. If your bare hands do touch the peppers, wash your hands and nails well with soap and warm water.
