Peel and slice plantains into 1" chunks.
Pour enough oil in a frying pan so that it is about ⅛" deep. Put heat on medium-high. When oil it hot, lightly fry plantains on one side, then flip. Once the second side is lightly fried, remove and place on a plate. Don't let them brown too much because they will be fried again.
Using the flat bottom of a large measuring cup, press the plantain into a flat disk about ¼" thick.
Return the smashed plantains to the frying pan, browning each side a bit more. Remove and place on a paper towel to absorb oil. Sprinkle with salt while it is still hot.
Serve with dips like guacamole, salsa or shredded pork or beef.
