Sometimes called the Hunter's Sauce; try this classic sauce with your next steak or roast.
Preheat large skillet on medium-low heat; coat with pan spray. Add onion, carrot, celery; cover and cook 10 minutes until vegetables are soft, stirring occasionally.
Increase heat to medium-high. Add wine to skillet; cook 3 to 4 minutes until liquid is reduced to a syrupy mixture. Add broth, bay leaves, thyme and peppercorns; cook 12 to 15 minutes until sauce is reduced to 1 cup. Strain sauce; discard vegetables and return sauce to same skillet. Reduce heat to medium-low. Stir in tomato paste; cook 2 minutes until glossy. Stir in butter and mix until incorporated; keep warm. Season with salt and pepper, as desired.
