Beef and Potato Burritos

This is adapted from Martha Stewart's Every Day Food magazine. Basically I've eliminated the jalapeno. My husband can't tolerate the heat. You can find the original recipe here.

Serves 4
INGREDIENTS:
1 large baking potato (You can also use dehydrated potatoes here. Just rehydrate beforehand and follow the same instructions)
2 tablespoons vegetable oil, such as safflower
3/4 pound ground beef
1 onion, chopped
1 can (14 ounces) chopped tomatoes with juice
1 1/2 teaspoons ground cumin
2 teaspoons paprika
Coarse salt
4 flour tortillas (10-inch)
1/4 cup sour cream
1/2 head iceberg lettuce, shredded
1/4 cup grated Monterey Jack
1/4 cup fresh cilantro (optional)
1 lime, plus wedges for garnish

DIRECTIONS:

1. Peel potatoes; cut into 1/2-inch dice. In a large saucepan, heat oil over medium heat. Add potato; cook, stirring occasionally, until golden brown, about 6 minutes.
2. Add beef and onion; cook, breaking up meat with a spoon, until beef is thoroughly browned, about 4 minutes. Add tomatoes and juice, cumin, paprika, and 1 teaspoon salt; cook until liquid has evaporated, about 6 minutes.
3. Heat tortillas, one at a time, in a dry skillet over medium-high heat, turning once, until lightly browned, about 10 seconds.
4. Leaving space on bottom and sides, layer tortillas with sour cream, lettuce, beef mixture, cheese, and cilantro, if using; squeeze lime juice on top. Fold bottom upward, covering filling by 2 inches. Fold each side to overlap, leaving the top end open. Serve garnished with lime wedges.
