Preheat your oven to 375°F (190°C).
Clean the portabella mushrooms by removing the stems and gently scraping out the gills with a spoon.
Brush the mushrooms with olive oil and place them on a baking sheet.
In a pan, heat the remaining olive oil over medium heat.
Dice the chicken breast into small pieces and add to the pan. Cook until the chicken is no longer pink.
Finely chop the celery, carrot, bell pepper, and onion. Add them to the pan with the chicken and sauté until the vegetables are tender.
Stir in the oregano and season with salt and pepper to taste.
Divide the chicken and vegetable mixture evenly among the mushroom caps.
Top each stuffed mushroom with shredded mozzarella cheese.
Bake in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the cheese is melted and bubbly.
Remove from the oven and let cool slightly before serving.
