Warm the olive oil in a large skillet (cast iron works well) over medium heat. Add the chopped onion and bell pepper and cook for 4–5 minutes, stirring occasionally, until softened and the onion is translucent. Lower the heat if they begin to brown too quickly.
1 tablespoon olive oil, 1 medium yellow onion, 1 red bell pepper
Stir in the minced garlic and cook for 30–60 seconds, stirring constantly, just until fragrant. Do not let the garlic burn.
2 cloves garlic
Push the veggies to the edges of the skillet and add the ground bison to the center. Break it into small pieces with a wooden spoon or spatula and season with the salt and black pepper. Cook for 5–7 minutes, stirring and crumbling, until the bison is no longer pink. Bison cooks faster than beef, so avoid overcooking.
1 pound ground bison, 1 teaspoon kosher salt, 1/2 teaspoon black pepper
Sprinkle the cumin, smoked paprika, chili powder, and crushed red pepper flakes (if using) over the meat and veggies. Stir well to coat and cook for about 1 minute to lightly toast the spices and deepen their flavor.
1 1/2 teaspoons ground cumin, 1 teaspoon smoked paprika, 1/2 teaspoon chili powder, 1/4 teaspoon crushed red pepper flakes
Pour in the fire-roasted diced tomatoes with their juices and the broth. Stir in the tomato paste until fully dissolved. Bring the mixture to a gentle simmer over medium heat; you should see small bubbles around the edges, not a rapid boil.
14.5 ounces fire-roasted diced tomatoes, 1/2 cup low-sodium beef broth, 1 tablespoon tomato paste
Stir in the rinsed and drained black beans, being gentle so they do not mash. Let the skillet simmer uncovered for 8–10 minutes, stirring occasionally, until the sauce thickens slightly. If the mixture becomes too thick, add a splash of broth or water.
15 ounces black beans
Turn off the heat. Stir in the apple cider vinegar or lime juice and the chopped cilantro or parsley. Taste and adjust seasoning, adding more salt, pepper, or lime as needed.
1 teaspoon apple cider vinegar, 1/4 cup fresh cilantro
Serve the bison mixture in warm tortillas for tacos, over rice, quinoa, or cauliflower rice, tucked into crisp lettuce leaves, or spooned over baked potatoes or sweet potatoes. Top with shredded cheese, avocado, Greek yogurt or sour cream, salsa, and hot sauce as desired.
