Salsa you'll want to eat with a spoon

This "salsa" from my friend Lisa is almost more of a salad. I suppose you could use chips to get it to your mouth but I prefer a serving spoon. YUM!

2 avacados
4-5 roma tomatoes
1/2 purple onion
1 can drained black beans (I make my own)
1 can white shoepeg corn
1T red wine vinegar
3-4T lime juice
2T olive oil
1t salt
1/2t pepper
1/2 package ranch dressing mix
