Peach Margarita Salsa

It's margarita month and the reviews on this have been 
outstanding.  It tastes just like a margarita!

1/2 cup chopped mild or sweet onion
2 cups diced peaches (mangos are good too)
1-2 Tbsps minced, seeded serranos (or other small chili)
2 Tbsps chopped fresh cilantro
3 Tbsps tequila or orange juice or orange liqueur
1 Tbsp finely grated lime peel
2 Tbsp lime juice
1/4 tsp ground cumin

Mix all ingredients and let stand 30 minutes.  This 
salsa is great served warm over beef.
