Grilled Filet Mignon with Chipotle Caramelized Onions

For caramelized onions, combine onions, pepper sauce, broth, vinegar, oil, garlic and brown sugar in a nonstick skillet.  Cook onion mixture on medium heat, covered, for 15 to 20 minutes, stirring occasionally until onions are caramelized and most of liquid is evaporated.  Remove from heat and set aside.

Rub salt and pepper onto both sides of filet.  Grill to desired doneness, 5 to 7 minutes each side for medium-rare meat.  Remove from grill; let meat rest for a few minutes.

Top each filet with chipotle caramelized onions.
