Wash the tomatoes and gently pierce each one 2 or 3 times with a small skewer.
Place tomatoes in a bowl with the tequila and limes, cover and chill for at least 3 hrs- (I usually let them marinate over night) stirring them once or twice.
To serve, drain the tequila- mound the tomatoes in a bowl and serve with coarse salt mixed with the lemon peel for dipping.
