Stir together the taco seasoning and beans and spread a spoonful down the middle of each tortilla.
Sprinkle with cheese.
Cover bottom of pan with oil, place over medium low heat and gently place taquitos in pan, and fry while turning to get each side golden brown.
It takes less than a minute for each side depending on how hot your pan and oil are (I have an electric stove and had it set between 2 and 3). Using tongs for this helps keep your burritos closed, and watch out for popping oil!
Drain on a plate lined with paper towels.
Let cool for a few minutes and serve with sour cream and salsa.
