Helpful Kitchen Tips
- Brown the chicken first to lock in juices before adding the vegetables.
- Let the dish simmer gently to allow the flavors to meld together.
Step 1
Warm some olive oil in a skillet over medium-high heat. Toss in the chicken and onion, cooking them until the chicken is just a little pink in the middle, which should take about 3 to 5 minutes. Next, add the yellow squash, green zucchini, red bell pepper, and mushrooms. Give everything a good stir and let it cook until the veggies start to soften, around 4 minutes.

Step 2
Then, throw in the garlic and keep stirring frequently until you can really smell that lovely garlic aroma, about 3 more minutes. Pour in the chicken stock and stir in the tomato paste along with the herbes de Provence, cumin, oregano, and celery salt. Mix everything well.

Step 3
Keep cooking and stirring, adding a splash more liquid if it looks too dry, until the vegetables reach the tenderness you like—this usually takes between 4 and 8 minutes. Finally, taste and season with salt and pepper to finish it off.
