ceviche style shrimp and avocado tacos

"Saw this in my Cooking Light Magazine this month...ran out and bought a couple of avocados! We loved this!"

Finely grate rind from limes to measure 1 tbls; juice limes to measure 1/4 cup.
Place rind and juice in a large bowl.
Add tomato and remaining ingredients this is where I also added a jalapeno -- chopped really fine! (except tortillas); toss well to combine.
Cover and chill for 15 minutes, stirring occasionally.
Heat tortillas (I sprayed grill with non stick spray -- and grill tortillas).
Once again -- recipe says it will feed 6 -- embarrassed to say -- it didn't!
****UPDATE****.
I really enjoyed this mixture on a bed of lettuce! Made a great salad!
