You will cook sweet potatoes in a separate skillet from the taco mixture:  Heat a large skillet over medium heat and add 1-2 Tbsp cooking fat.  Add diced sweet potatoes and cook 1 minute uncovered, stir, then cook 3-4 minutes covered (to soften), then 3 minutes uncovered to brown.  Remove from heat until ready to mix with beef mixture.

In a separate skillet, heat coconut oil or other cooking fat over medium heat, and add onions, cook until translucent. Add red bell pepper, jalapeno and garlic, stir to cook evenly until softened.

Crumble in the ground beef, then add the salt, taco seasoning and chipotle powder and stir to combine well. Once beef is browned and veggies soft, drain a bit of grease if necessary, and add in the cooked sweet potatoes. 

Gently stir potatoes with taco mixture to combine, then serve with desired toppings: salsa, sliced avocado, lime juice, cilantro, chipotle ranch* (see note for recipe), fried eggs, etc. Enjoy!
