Prepare rice per product instructions.
(For instant pot, rinse rice in a fine mesh strainer until water runs clear. Combine rice and water and cook for 26 minutes on rice setting. When done, manually release pressure and let rice sit in covered pot for 20 more minutes.)
While rice is cooking, brown ground beef on stovetop and drain fat.
While rice and beef are cooking, wash and chop vegetables and set green beans aside. Combine sweetpotatoes and carrots in a pot and cover with water. Bring to a boil, reduce heat and continue boiling for 6 minutes. Add green beans and boil for another 4 minutes. Carefully strain water from cooked vegetables and set aside.
Allow all ingredients to cool.
Combine ingredients in a food processor in batches using 3 parts beef, 2 parts vegetables, 1 part rice. (This will need to be done in several batches to avoid overcrowding the work bowl.) Blend for 5-10 seconds until combined.
