Add oil, lime juice and seasoning to a large salad bowl and combine well.
Add all other ingredients and toss well. Serve cold.
Notes
Tips
Feel free to use just one kind of beans, or use whatever cooked beans you have on hand. I've made this salad many different ways, and it's always delicious.
If you don't have any fresh limes, use bottled lime juice or apple cider vinegar instead.
For a lighter salad, try reducing the olive oil and using more lime juice instead.
Storage
The salad keeps well for a day in the fridge. I recommend adding the avocado right before serving though, it tends to turn brown otherwise.
