Cook rice according to package directions, omitting salt and fat.
While rice cooks, combine salsa and black beans in a small saucepan; cook over medium heat 5 minutes or until thoroughly heated. Stack tortillas; wrap stack in damp paper towels. Microwave at high 25 seconds or until warm.
Spread 1 tablespoon bean dip over each tortilla; top each tortilla with 1/4 cup rice, 1/3 cup black bean mixture, 2 tablespoons cheese, 1 avocado slice, and 2 cilantro sprigs; roll up. Serve with lime wedges, if desired.
