We make this taco meat all the time. Use it to fill corn or flour tortilla shells, so if you are going grain-free make a taco salad out of it. We've even used it on top of nachos. So many options!
Brown the meat in a large skillet; add onion and jalapeno and saute a few minutes until tender. Add tomato sauce, cilantro, cumin, garlic powder, chili powder, and fresh lime. Season with salt and pepper to taste.
Simmer for 5-10 minutes. If the mixture starts to look dry, add 1-2 Tbsp of water and stir to combine.
Now fill those shells or top those salads!
