Preheat oven to 375 degrees. Cover baking sheet with parchment paper, place washed and dried sweet potatoes on baking sheet and bake for 30-40 minutes or until fork pokes through to the middle easily.
Add ground beef to a medium skillet and begin cooking over medium-high heat. Using a spatula, break meat into small pieces. Once meat is cooked through, add all seasoning, stirring together.
On a glass plate place one sweet potato. Using a knife slice the top of the potato open lengthwise. Using a fork, mash the inside of the sweet potato a little and create a “well” to make room for the taco meat. Add desired amount of taco meat, top with tomatoes, jalapeno slices, avocado, fresh cilantro, and scallions. Using one lime wedge, squeeze fresh juice over the top.
Add shredded cheese and sour-cream of choice for non-Whole30 version.
