Preheat the oven to 425℉. Line a sheet pan with tin foil and place a wire rack on top of it.
In a small saucepan, heat the refried beans, butter, and salt on medium-high heat until the butter melts and everything is combined, about 2-4 minutes.
Remove the beans from the stove.
Combine the beans, hot sauce, cheese, green chile, sour cream, and taco seasoning in a large bowl.
Place the tortillas in the microwave for 18 seconds each so they are easier to roll.
Place ¼ cup of the bean and cheese mixture in the center of the tortilla and spread it evenly over the surface.
Then, roll up the tortilla and place it seam side down on top of the wire rack.
Once the taquitos are all rolled up, brush the tops with the olive oil.
Bake for 10-15 minutes.
Serve and enjoy!
