Four Rule Grilled Open Melts - Stewed Pears . com

bread - preferably crunchy that will hold its shape; ciabatta, pane di casa, rye, baguette
cheese - mozzarella, or a mix of mozzarella/cheddar
other ingredients - if you can put it on a pizza, you can put it on a melt

ham, tomato, cheese (a little mustard on the ham if you like that)
tuna (and, stay with me, if you like pineapple on pizza you will like it with tuna)
a mix of tuna, mayo and finely chopped red onion
corned beef with finely sliced dill pickle
meat lovers - hot salami, ham, a little BBQ sauce
pulled pork, finely chopped red onion, thin sliced red capsicum
mushrooms - by themselves, with meat, or other vegetables

Slice the bread to your desired thickness. Toast on one side under the grill. Then very lightly toast on the other side.
You can butter the very lightly toasted side now (optional). It does add a little depth to the flavour, not gonna lie.
Add ingredients. To ensure they warm through, you may need to put them on layer by layer. They don't need long. You'll need to watch to ensure the bread doesn't burn.
Add the cheese. Ensure it overlaps the ingredients so they don't slide off when you take a bite later. Ingredients in lap = no no. Season now.
Grill until cheese is melted and bubbling. Season again. Sprinkle with herbs if you like.
