Cheesy beef burritos

My wife immediately showed displeasure at my cooking a been burrito, but she changed when we ate these.  In fact, we both had the delicious leftovers the next day.

2 tsp chili powder
1 can (15 oz) black beans, drained, rinsed
1/2 cup salsa
3/4 cup shredded sharp cheddar cheese
4 flour tortillas (10 inch)
1/2 cup sour cream
1 tomato, chopped
1 cup shredded romaine lettuce
