In bowl, combine Masarica, Adobo and 2 cups of water. Mix until water is absorbed. Using hands, knead Masarica mixture, adding remaining water a little at a time, until moist dough is formed. You may not need all the water.
Using hands, roll 3 tablespoons dough into ball. Flatten into disk that measures 5” round and 1/8” thick; repeat with remaining dough to form 16 disks, cover dough and disks with damp towel as you work. Spread 1 tablespoon refried beans or cheese evenly over one round . Season with Adobo. Cover with another round; crimp the bottom edge over the top to seal. As a variation, you can combine both beans and cheese in same pupusa. Repeat using remaining dough, beans and cheese until 8 pupusas are formed.
On a medium hot, lightly oiled griddle or skillet cook pupusas until browned on both sides, flipping once, 6-8 minutes.
Serve hot with cabbage salad accompaniment.
