Cut a few sweet potatoes into small cubes. Mix in just a little olive oil (or oil of choice) along with salt, pepper, garlic powder and onion powder. Cook at 450 degrees in a single layer for 30 minutes, mixing them around a bit half way. If you want them a bit more browned, simply turn on the broiler for a few minutes at the end watching to make sure then don’t burn.
Remove and eat - keep the rest in the fridge to quickly heat for other meals. I use them for side dishes along with mixing them into a morning scramble. They are delicious and reheat pretty well. They don’t seem to get as mushy as simply cooking them whole.
