Sweet Potato Burritos

I used to make these ALL the time, and then stopped, because I was eating 3 at a time! My friend, Amy, made these today, and reminded me that I should post this.

Sweet Potato Burritos
Ingredients:
5 cups peeled cubed sweet potatoes (I use canned, and drain and rinse, thus omitting the first step.)
1/2 teaspoon salt
2 teaspoons canola or other vegetable oil
3-1/2 cups diced onions
4 large garlic cloves, minced or pressed
1 Tablespoon minced fresh green chile ( I omit for the boys, but then use green salsa, at the end!)
4 teaspoons ground cumin
4 teaspoons ground coriander
4-1/2 cups cooked black beans (three 15-ounce cans, drained)
2/3 cup lightly packed cilantro leaves
2 Tablespoons fresh lime juice
1 teaspoon salt
8 eight-inch flour tortillas
Fresh tomato salsa or jarred (I prefer salsa verde.)
Preparation:
Preheat the oven to 350 degrees F.
Place the sweet potatoes in a medium saucepan with the salt and water to cover. Cover and bring to a boil, then simmer until tender, about 10 minutes. Drain and set aside.
While the sweet potatoes are cooking, warm the oil in a medium skillet or saucepan and add the onions, garlic, and chiles. Cover and cook on medium-low heat, stirring occasionally, until the onions are tender, about 7 minutes. Add the cumin and coriandeer and cook for 2 to 3 minutes longer, stirring frequently. Remove from the heat and set aside.
In a food processor, combine the black beans, cilantro, lime juice, salt, and cooked sweet potatoes and puree until smooth. (You can also mash the ingredients in a large bowl by hand using a potato masher. The result will be a less smooth but nicely textured filling.)
Transfer the sweet potato mixture to a large mixing bowl and mix in the cooked onions and spices. Lightly oil a large baking dish. Spoon about 2/3 to 3/4 cup of the filling in the center of each tortilla, roll it up, and place it, seam side down, in the baking dish. Cover tightly with foil and bake for about 30 minutes, until piping hot. Serve topped with salsa.
Yield: 4 to 6 servings
