Add tomatillos, garlic, and chile; cook 7 minutes. Drain and rinse with cold water. Combine tomatillos, garlic, chile, chopped cilantro, onion, lime juice, and 1/4 teaspoon salt in a food processor or blender; pulse 4 to 5 times or until coarsely chopped.

Arrange crumbs on a baking sheet; bake at 350° for 3 minutes or until lightly browned. Cool completely.     Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/2-inch thickness using a meat mallet or rolling pin.

Dip chicken in egg; dredge in breadcrumbs.     Heat oil in a large nonstick skillet over medium-high heat. Add chicken; cook 4 minutes on each side or until done.
