1 Tbsp olive oil
1/2 cup minced carrots (can sub chopped bell pepper)
1 cup chopped onion (about 1 medium onion)
1/2 cup chopped celery
2 cloves garlic, minced
1 1/4 lb ground beef
1/2 cup ketchup
2 cups tomato sauce (or 1 15-ounce can whole tomatoes, puréed)
1 Tbsp Worcestershire sauce
1 Tbsp red wine vinegar
2 Tbsp brown sugar
Pinch ground cloves
1/2 teaspoon dried thyme
Pinch cayenne pepper
2 turns of freshly ground black pepper
4 hamburger buns
1. Heat olive oil in a large sauté pan on medium high heat. Add the carrots and sauté until soft. (If you are using bell pepper instead of carrots, add those at the same time as the onions.) Add the chopped onion and celery. Cook, stirring occasionally until onions are translucent, about 5 more minutes. Add the minced garlic and cook for 30 more seconds. Remove from heat. Remove vegetables from the pan to a medium sized bowl, set aside.
2. Using the same pan (or you can cook the meat at the same time as the vegetables in a separate pan to save time), generously salt the bottom of the pan (about 1/4 to 1/2 teaspoon). Heat the pan on high. Crumble the ground beef into the pan and cook until entirely browned.
3. Return the vegetables to the pan. Add the ketchup, tomato sauce, Worcestershire sauce, vinegar and brown sugar to the pan. Stir to mix well. Add ground cloves, thyme, and cayenne pepper. Lower the heat to medium low and let simmer for 10 minutes. Adjust seasonings to taste (I added salt). Serves 4.
