• 2 c. thinly sliced green cabbage
• 2 c. thinly sliced red cabbage
• 6 whole-wheat hamburger buns, split and lightly toasted
Heat oil in a large skillet over medium-high heat. Add the turkey and cook, breaking any lumps up with the back of a wooden spoon, until cooked through, about 5 minutes. Add the onion and the bell pepper and continue to cook until the vegetables are softened and the turkey is beginning to brown. Add the tomato paste and continue to cook, stirring, for another 2 minutes, or until the paste begins to turn a rusty color.
Reduce heat to medium and add the water, tomato sauce, 1/3 cup barbecue sauce, 2 tablespoons red vinegar, salt, black pepper and red pepper flakes. Stir to combine and reduce heat to low and simmer for 20 minutes, stirring frequently.
