Put one cup of water in the bottom of your Instant Pot, stack pans on the trivot they come with and place inside the Instant Pot. Be careful when layering, don't overfill your pans or you won't be able to stack them as neatly. If they're too full to stack neatly cover the tops with foil and place your Instant Pot trivot in-between the pans when stacking.
Place the lid on your Instant Pot and make sure the vent valve is set to the SEALING position. Select the MANUAL function, cook for 10 minutes. When the pot is done quickly release the pressure.
The cheese will be melted but if you want it to be crisp on top put it in your oven to BROIL for a couple minutes.
Serve by themselves or over a bed of lettuce with a sprinkling of tomato, cilantro and avocado! Enjoy!
