How to Make It
Cut jalapeños in half lengthwise; discard seeds and membranes. Place pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil 4 minutes or until blackened. Place in a zip-top plastic bag; seal. Let stand 5 minutes. Peel and chop. Reduce oven temperature to 375°.
Heat a large nonstick skillet over medium-high heat. Add the onion, bell peppers, and garlic; sauté 6 minutes. Add tomato, cumin, and coriander; cook 3 minutes. Add jalapeño and beans; cook 3 minutes. Remove from heat; cool 10 minutes. Stir in cilantro, sour cream, and egg.
Spread 3 tablespoons salsa in bottom of a 13 x 9-inch baking dish coated with cooking spray. Arrange 4 noodles slightly overlapping over salsa, and top with half of the bean mixture, 1/2 cup cheese, and 3 tablespoons salsa. Repeat the layers, ending with noodles. Spread remaining salsa over noodles, and sprinkle with 1/2 cup cheese. Cover and bake at 375° for 30 minutes. Uncover and bake an additional 15 minutes or until cheese melts. Let stand 5 minutes.
