Peel sweet potatoes and chop into same-sized pieces. Place into about 10 cups of water, with 1 tablespoon salt, and boil for at least20 minutes. Once they are fork-tender, they are ready.
While potatoes are boiling, prepare other ingredients and place in a bowl:-rinse cans of beans and corn-add onion, garlic, and cilantro
Once potatoes are done, drain and place them into a very largebowl. Mash them until smooth.
Add remaining salt, pepper, chipotle powder, and paprika. Stir.
Add all vegetables to the potatoes and stir until well-mixed.
Spray an oven-safe dish and add the casserole. Cook at 350degrees for 20 minutes.
Add more cilantro on the top when serving, if you like cilantro.
