Sweet Potato Chili
In a large pot or dutch oven, heat the oil over medium-high heat. If using a roast, sear until lightly browned on all sides.
If using ground beef, cook thoroughly until no longer pink. Add onion and cook 2-3 minutes, or until onions just begin to soften.
Remove pot from heat and use a large spoon to move the meat and onion mixture into the slow cooker.
Add sweet potatoes, diced tomatoes, garlic, spices, and salt, and stir well. Cover and cook on low 4 to 6 hours, or until meat and veggies are tender.
