Bean & Cheese Stuffed Pupusas

In a medium bowl, stir together the masa harina and salt. Stir in the hot water to form a soft dough; cover and let stand 10 minutes.

Place a large piece of plastic wrap on a work surface. Divide the dough into 8 equal portions, shaping each into a ball. (If the dough feels too wet, work in another tablespoon of masa harina.) Place the dough balls on the plastic wrap. Flatten 4 dough balls into a 3-in circle. Arrange 1 tbsp refried beans and 1 tbsp cheese in the center of each circle. Using plastic wrap, bring the edges of the dough over the filling. Coat hands with cooking spray and pat the dough over the filling to completely enclose it. Gently flatten each filled dough piece into a 4-in circle. Coat both sides of pupusas with cooking spray.

Heat a large nonstick skillet over medium-high heat. Add 4 filled dough pieces to the pan; cook until golden brown and crisp on the outside, 3 to 4 minutes per side. Repeat the process with the remaining dough and filling to make 8 pupusas.
