In a large bowl, mix together masa harina flour, water, and salt.
Form into a dough. You might have to add more water if the dough is crumbly and dry. You want it to be a moist play dough type consistency.
Form into 4 equal sized balls.
Take a gallon sized ziplock bag and cut it apart from the seams so you have 2 pieces.Lay one of the ziplock bags the tortilla press. Pt one of the dough balls in the center of the press, with the other ziplock bag over the top.
Press down until it is about 1/4" thick.
Do this with the other 3 dough balls.
On a well oiled griddle over medium high heat, add the 4 cylinders of pressed dough.
Cook on each side for 2-3 minutes.
Now for assembly. Spread out the refried beans first. This will be the glue. Then add the meat. I used some left over roast chicken. From here on, put whatever other toppings that you like. I put on some crumbled queso fresco, sour cream, cilantro, radish, avocado, pickled red onion, and a red hot sauce.
