First you need a good cantina type of drink. You can't go wrong with any of these. Click the link and scroll down - why on my blog the drink would come after the food is beyond even me but they are there, I promise!
Classic Frozen Margarita
Salty Chihuahua (No actual chihuahuas were harmed in the making of this drink)
Now inevitably people ask me what Ro-Tel is - it's a can of diced tomatoes and green chiles. Be careful - you can buy it in many varieties and the hot and super hot? Really are hot and super hot. If you don't have Ro-Tel in your area, you can substitute canned tomatoes with green chiles - just make sure they are chopped fairly small.
You want to know what goes great with salsa and guacamole besides tacos? These little Southwestern Egg Rolls.
Cilantro Lime Fish Tacos
Crispy Shrimp Tacos
Shredded Beef & Potato Tacos
Roasted Pork & Potato Chile Verde
Taco Soup - I think you should know this is the number one most requested dish in my house, fiesta or not!
Now off to work on some kind of super fabulous Cinco de Mayo dessert....
