Creating your antojitos is easy if you follow these steps:

1. Make the Dough: In a bowl, combine masa harina and salt. Gradually add warm water and mix until a smooth dough forms.
2. Divide the Dough: Split the dough into equal portions, depending on how large you want your antojitos to be.
3. Flatten the Dough: Use a tortilla press or your hands to flatten each portion into a small circle.
4. Fill the Dough: Place shredded cheese and your choice of protein in the center of each circle. Add a sprinkle of onions and cilantro for an extra flavor burst.
5. Seal the Dough: Fold the dough over the filling, pinching the edges to ensure it is well-sealed.
6. Heat the Oil: In a frying pan, heat vegetable oil over medium heat until hot.
7. Fry the Antojitos: Carefully place the filled dough into the hot oil. Fry until golden brown on both sides, about 3-4 minutes per side.
8. Drain Excess Oil: Once fried, place the antojitos on a paper towel-lined plate to absorb excess oil.
9. Serve Hot: Plate the antojitos and prepare to serve with your favorite toppings like salsa or avocado.
