Begin by preparing your taco skillet. Heat a large skillet over medium high heat, add oil once hot, then add your vegetables: sweet potatoes, onion, bell pepper.
Cook the veggies for 5-7 minutes, or until softened. Now add the ground beef, and cook for another 5-7 minutes, or until ground beef is no longer pink. Drain any water or fat once the meat is finished.
Now add in spices and salt, tomatoes, then vinegar. Coat the veggies and meat completely, adding water if needed. Simmer to let flavors meld for at least another 5 minutes.
Now make your cashew sauce (optional). Drain the cashews. Add cashews, broth or water, jalapeños, garlic, nutritional yeast, and hot sauce to a high powered blender. Blend until completely smooth, adding additional water if too thick.
Serve your skillet with extra toppings: salsa, guacamole or avocado, and additional jalapeños. Top with cashew sauce (if using).
