Slice the chicken breast into strips, then season with salt and pepper.
Heat oil in a pan and sear the chicken on all sides, then remove it and set aside.
In the same pan, sauté the diced onion, then add the garlic.
Add the sliced mushrooms and cook until slightly golden.
Add the sliced zucchini and the bell pepper cut into strips.
Season with paprika and thyme, then return the chicken to the pan.
If you prefer a creamier result, stir in a little cream or yogurt.
Cook everything together for 5 to 7 minutes until fully cooked through.
