Salad of Black Beans and Rice

This is a love it or hate it dish at my house. I love it. (-: So, this will be my lunch for a week or I may share some with a neighbor.

3 c. cooked rice, 1 c. raw (I use white but you can use brown, if you prefer.)
1/2 c. chopped onion
1-16 oz. can black beans, rinsed (If I feel industrious, I cook dried beans.)
1 c. chopped sweet pepper (Red and green mixed are good.)
1/4 c. chopped parsley (Can use dry. This evening, I chopped a bunch in the food processor and dried the remainder for later use in a 200 degree oven.)

Dressing:

1/3 c. salad oil
1/4 c. fresh lime juice
1 t. ground coriander
Salt and pepper to taste

Garnishes:

Avocado
Chopped parsley
Paprika
