Preheat the oven to 400 degrees F.
Add the sweet potatoes to a sheet pan. Poke holes in them with a fork and then drizzle the avocado oil, salt, and garlic powder on top. Rub the oil over the potatoes to evenly coat. Add to the oven and bake for 45 minutes to an hour, or until the potatoes can be easily pierced with a fork.
Meanwhile, brown the ground beef and add taco seasoning. Prepare according to the package directions.
To make the guacamole, cut avocados in half, scoop out the meaty part, and put them into a medium-sized bowl. Mash avocados using a fork or potato masher. You can leave it chunky, or make it smooth, whichever you prefer. Add the remaining ingredients: red onions, cilantro, cumin, garlic powder, salt, and lime juice. Stir/mash to combine
When the potatoes are tender, remove them from the oven and let them cool slightly so they are easier to handle. To plate, take one sweet potato and cut it in half. Add in a scoop of ground beef and then add your desired toppings, such as tomatoes, red onion, pickled jalapeños, and salsa. Top with a scoop of guacamole and enjoy!
