Heat butter in a nonstick or cast-iron saute pan over medium heat. Add onions and cook until tender, about 5 minutes. Add chorizo to brown, season with salt and pepper.

Once browned, add rice and incorporate well.

In a bowl, whisk eggs until well blended. Add eggs to the pan with the chorizo mixture, spreading evenly.

Top with cheese, then cover with a tortilla.

Make sure nothing is sticking to the pan by gently using a spatula or fork.

Using a plate, flip the pan over onto it to turn the tortilla.

Give the pan a quick wipe, then place the tortilla back into the pan, tortilla side down, then fold in half.

While that side is toasting, rotate the tortilla a ¼ turn every few minutes to make sure it’s evenly toasted.

After about 5-6 minutes, flip the tortilla to toast the other side, rotating as you did before.

Once toasted to your preference, remove from the pan.

ENJOY!
