To prepare stuffed jalapeos, place peppers on a foil-lined baking sheet; broil 12 minutes or until blackened, turning occasionally.
Place in a zip-top plastic bag; seal.
Let stand 15 minutes; peel jalapeos.
Cut a lengthwise slit in each, discarding stems, seeds, and membranes.
Place a medium nonstick skillet coated with cooking spray over low heat until hot.
Add bell pepper, onion, and garlic, and cook 5 minutes or until soft.
Remove from heat; stir in crabmeat, 1 tablespoon cilantro, and 1/4 teaspoon salt. Divide crab mixture evenly among jalapeos (each will be very full).
Preheat oven to 37
Beat the egg whites in a medium bowl at high speed of a mixer until soft peaks form. Fold in yogurt.
Combine breadcrumbs, cornmeal, 1 teaspoon salt, and garlic powder in a small bowl. Dip each stuffed jalapeo in the egg white mixture; dredge in the breadcrumb mixture.
Place the breaded jalapeos on a baking sheet coated with cooking spray. Lightly spray jalapeos with cooking spray.
Bake at 375 for 15 minutes or until golden.
To prepare avocado dunk, place avocado and remaining ingredients in a food processor or blender, and process until smooth.
