Heat the oil in a pot then pour in the flour and cook, whisking constantly, for a minute or so.
Mix in the cumin, garlic powder, chili powder, oregano, and salt.
Next pour in the broth, whisking all the time to get rid of clumps.
Keep cooking for 15 minutes or until thickened.
Preheat the oven to 350 degrees F.
Dip the corn tortillas in this sauce one by one until pliable.
Immediately put them in a greased 7 x 11-inch baking pan.
Sprinkle Mexican blend cheese on top and roll the tortilla around it.
Continue until they’re all rolled up with cheese inside.
Pour the remaining sauce over the top, sprinkle on more cheese, and bake for 20 to 25 minutes.
