Step 1

In a large pan over medium heat add a splash of olive oil alongside onion, jalapeño and garlic. Fry until they soften, then add in chorizo and continue frying until the chorizo begins to crisp. Remove everything from the pan and rest on paper towels. Wipe out pan.

Step 2

Spread one side of each of the slices of bread with butter. Flip half over them over so they're butter-side-down. To those slices, add Monterey Jack, followed by chorizo, then sliced avocado and finish with mozzarella. Add bread on top butter-side-up.

Step 3

In two batches, add sandwiches to the pan over medium heat and fry both sides until golden with the cheese melted in the centre.
