Peppers, zucchini, chicken filet and couscous

Today I made this simple and fast stir fry dish. I made this with couscous but you also can take rice if you're not familiar with couscous.

Ingredients:
2 red peppers
1 zucchini, I had a yellow one
1 red onion
2 chicken filets
Cornstarch or cornflower
Olive oil
Couscous or rice
Salt
Pepper
Coriander

Directions:
Cut the onion, peppers and zucchini in pieces. Cut the chicken filet in small pieces. Put the chicken filet in a bowl; add salt, pepper, olive oil and just a bit of cornstarch, this keeps the chicken more tender. Fry the chicken filet in some hot oil. Take the chicken out and put it aside. Fry the onion and the peppers a few minutes and add the zucchini. Put the chicken filet back in and stir fry this all together a few minutes. Cut the coriander leaves in small pieces and add this at the end when your dish is ready. Cook the couscous according the instructions on the package.
