Can a margarita become even more of a tropical delight? With bananas, I sure think so.
Pour the sugar onto a small plate. Moisten up the rims of your glasses, then press them into the sugar. Yay, sugared rims!
Combine the tequila, limeade, Triple Sec and ice in the pitcher of a blender. Blend that stuff until it's a smooth mixture. Add the bananas to the mix and blend it up again until it's smooth again. Pour into glasses and serve.
