This is a great recipe for hot summer days when you just don't want to heat up the house with the oven, or yourself with hot food. Use more avocados or tomatoes depending on what is least expensive and in season. This could also be tossed together like a salad, or served in individual dishes of rice with the other ingredients used as toppings. I have also heard of this called "California Sushi" with the ingredients used to make meatless sushi rolls.
2-3 cups cooked rice
2 cans black beans, rinsed
2 avocados, cubed (place in lemon water to prevent browning)
2 tomatoes, cubed
2-3 diced green onions
1 lb chicken, cubed
Optional: Pita bread
Spread in layers or rings on a platter, place sour cream and salsa in middle. Serve with Pita Bread if desired.
