To make the fried tortillas, pour enough oil in a heavy skillet to come up 1/2 inch up the sides and heat to 350°F, about 5 minutes. If you don’t have a thermometer, you can test the temperature by sticking a wooden spoon into the oil. If it bubbles around the spoon, it should be ready for frying. Line a large plate or sheet with paper towels.
Fry the tortillas on each side until crisp and lightly browned, about 1 minute. Drain the fried tortillas on paper towels and lightly salt.
If not already warm, heat up the refried beans.
To assemble the chalupas, spread each fried tortilla with 1/4 cup of refried beans. Top with lettuce, tomatoes, and shredded cheese. Serve with guacamole, pickled jalapeños, and salsa on the side for garnishing.
