Pulse the pineapple in your blender until smooth. Remove all but 1/2 cup pineapple juice from the blender and reserve the extra for another round.

Add the lemon juice, lime juice, sugar, salt, and ice to the blender. Pulse until ice is crushed and smoothie-like consistency. Add the tequila and triple sec and pulse once or twice just to combine.

Serve in salt lined margarita galsses, if desired.
