I usually make them together, so I'll list the ingredients as such:
1 onion, diced
3 red bell peppers, diced
1 garlic clove
jalapenos (fresh or jarred), finely diced
2 cups black beans or 1 can
1 cup dried rice, cooked according to package directions
Saute onion and pepper in oil.
Peel and mash the avocado, and add about 1/4 of the onion/pepper mix. Add the juice from the lime. Mix and serve with tortillas.
Add garlic, cilantro and jalapenos to onion/pepper mix. Add beans and cooked rice, stir well.
There is an AWESOME salsa in Costa Rica called Lizano - if you can find this, it really makes the dish!
On that note - if anyone DOES find it, please comment and let me know where!
