Chop up all the vegetables. (Boring but necessary)
Place sweet potatoes, tomatoes, tomato sauce, onion, celery, water, chili powder, cumin, jalapenos, salt, black pepper, cayenne pepper, garlic powder, and onion powder in a slow cooker. Cook on high, stirring occasionally, for 5 hours.
Heat a large skillet over medium-high heat, place in a pat of coconut oil and cook ground beef until desired preparedness (should take about 10 minutes for medium)
Preheat over to 400 degrees and cook chicken for 25 to 30 minutes. Remove from the oven and slice into thin pieces or cubes.
Add cooked ground beef or turkey, chicken, and beans to sweet potato mixture in the slow cooker; cook until flavors have blended, 1 to 2 more hours.
If you want, slice up some avocado and place on top.
