Add half of Broccoli and Red Bell Pepper Mix, half of Lime Shrimp and half of cheese. Layer on remaining 3 tortilla halves, Broccoli and Red Bell Pepper Mix and Lime Shrimp. Pour remaining 1 1/4 cups sauce and cheese over shrimp. If not eating immediately, cover tightly and freeze. Otherwise, bake 20 minutes, covered with foil. Remove foil; bake until cheese bubbles, 10 minutes more.
