Rub sea salt and red pepper flakes or your seasoning of choice on tuna steaks (I also like to use fresh dill and lime juice)
Place steaks on a tray in your Instant Pot
Put 1/2 cup water in bottom of Instant Pot
Set cook time on manual or steam for 3 minutes, until the meat is cooked, but pink in the middle.
If you don't like pink meat, cook it a minute longer
NOTE: Cook longer for well-done. Tuna gets flakier as it cooks
Serve with favorite side dish. Enjoy!
