Pineapple Chicken

Rice and chicken dish that's sweet and yummy! It looks great and is very colorful and easy to make. I was playing around with pineapple and chicken and came up with this, it has all of my favorite items in it.

Ingredients
1 box instant five-minute rice
4 boneless, skinless chicken breasts
equal parts of olive oil & butter
salt & pepper to taste
1 red onion, diced
1 green bell pepper, diced
1 red bell pepper, diced
1 yellow bell pepper, diced
1 orange bell pepper, diced
1-2 lb. mushrooms, sliced
2 large cans pineapple chunks
pineapple juice
cornstarch

Directions
Prepare rice according to box directions. In a large skillet add butter and olive oil. Salt and pepper chicken to taste, add to pan, and cook chicken until done and golden brown. In the meantime, prepare your other ingredients, by dicing them. In a different large skillet add butter and oil to the pan for the veggies. Add the veggies and cook, add pineapple and juice to veggies while they are still a bit crunchy.
Mix together a rue of pineapple juice & cornstarch to thicken the sauce, and add to veggies. Serve rice and chicken side by side, and place sauce over both or either side.
