Fried onions and mushrooms covered in cheese and topped with lettuce, tomato, and crispy bread makes for a comforting, flavor-packed spin on the classic grilled cheese sandwich.
Add a swirl of oil and then add the onions and mushrooms. Season with salt and pepper and cook for 10 minutes. Add the sambal oelek and the garlic. Cook for another 5 minutes, stirring, until both the mushrooms and onions are soft and browned. Turn heat off and set aside (or transfer onions and mushrooms to a bowl to wait)
Heat another frying pan over medium heat (or use the one from the onions if you moved them to a bowl) Add oil and then add two slices of bread. Fry for 2-3 minutes per side. Remove from pan.
To assemble: Spread mayo on one slice of bread. Add the onion + mushrooms. Add the cheese slice, lettuce, and tomato. Season with salt and pepper. Add the remaining piece of bread. Slice in half and serve hot.
Notes
Use different vegetables if you want, whichever ones you like best. If they are watery ones, like zucchini, etc., make sure to cook them well.
