Wow. All I can say is this is the most flavorful and delicious breakfast burrito I've ever had. I didn't have any cheese or sour cream in the house, and even without it I absolutely loved this. I used small corn tortillas in place of flour tortillas, and I chopped up the potato instead of grating and left the skin on. This is a definite make-again recipe, and that doesn't happen very often for me. If you want to make these for dinner try adding chopped red pepper and/or corn and some crumbled chorizo sausauge with the onion. This is supposed to serve 4, but if you have guests you may want to double the recipe. Recipe courtesy of Spilling the Beans.
