Slice the brisket, warm if it's cold and set aside. Grate your cheese for the scrambled eggs. Heat your refried beans. Prepare your Pico De gallo.
Heat a large skillet or griddle to heat your flour tortillas. Meanwhile, beat your eggs, add a little salt and pepper and scramble in skillet with the melted butter. Add the cheese to the eggs while scrambling. Remove from the heat and set aside.
To assemble: Heat your flour tortilla by flipping back and forth on a heated griddle or a large skillet. Lay on a flat surface. In the middle of the tortilla, leaving room to fold on each side, apply a layer of refried beans. Then in strips...add the brisket, then the cheesy eggs, then the hashbrowns, and lastly a strip of the pico de gallo.
Fold each side in, then start rolling, tucking to make a tight roll, making sure the sides are secure, until the burrito is complete. Wrap in foil. I like to half, but serve anyway you want. Serve with your favorite salsa, more pico if you want, some sour cream and guacamole. Enjoy!
