Prepare the panini

• Rinse the beans and drain them well.
• Lay cheese on a slice of bread, add the beans, then top with more cheese.
• Close the sandwich and press it lightly.

Toast the panini

• Place the sandwich in a hot panini press or frying pan.
• Leave it much longer than you think is needed so the cheese melts and the bread crisps.
• Trim off any burnt edges if necessary.

Make the loaded sourdough version

• Sauté the sliced onion until golden.
• Butter the sourdough slices and layer with beans, sautéed onion, pickled jalapeño and cheese.
• Toast in the pan until golden and crisp.

Serve

• Cut the panini and serve with a spoonful of chili garlic hot sauce.
