Place the Masa Harina in a large bowl, pour in the salt, and water, and get in there with your hands, kneading until you have uniform dough. It should take only a minute or two, if it's dry, add a little more water, a teaspoon at a time. If it's sticky, work in a little more Masa Harina
Make 8 round balls, make 2- to 3-inch balls of dough, and place them one at a time in a resealable bag. Flatten with a rolling pin or use your hands, make a circle, and pinch side edges to make a lip on the masa circle.
Heat oil to 400 degrees F in a deep-fryer or large saucepan.
Fry dough in the hot oil until Sopes are just lightly browned, about 20-30 seconds per side.
Serve with rice on the side, and top with beans, cheese, salsa, or favorite topping.
