For Roasting the Sweet Potatoes first, follow this step. If not roasting, that is fine and go to step 2! Preheat oven to 400 degrees if roasting the potatoes. Sweet potatoes should be peeled and cut into 1/2" cubes. Toss the potatoes in 1 tablespoon of olive oil. Place on a sheet pan and roast for 20-30 minutes. They should be tender when poked with a fork. Set aside.
