Peel the casings off the sausage links as best you can and dice chorizo and half a large red onion.
Heat extra virgin olive oil in a large skillet set to medium heat. Add chorizo, onions and cook till sausage is brown and onions translucent.
Butter two slices of bread and place on a griddle set to medium low heat. Lightly brown both sides of the bread and set aside.
Lay out two slices of bread onto a clean surface. Sprinkle the queso cheese evenly on each slice followed by the fried chorizo and onions.
Top the bread slices with the browned bread that was set aside and carefully smush the sandwich down so everything holds together.
Sprinkled the cheddar cheese on top of the sandwich followed by jalapeños and a dash of cheddar covering the jalapeños. Cover each sandwich with the remaining slices of bread. Carefully smush down the sandwich.
Butter each side of the sandwich and place on a griddle set to medium heat. Brown each side of the sandwich. Be extra careful while flipping it over.
