Rinse the chicken and pat dry with paper towels. Season the chicken with salt and pepper. Heat a stainless steel roasting pan on the stove (you can use 2 burners) over medium high heat, and add a few tablespoons of olive oil.
Sear the chicken in the roasting pan skin-side down until lightly golden. Flip the chicken over, and turn off the stove.
To the chicken in the roasting pan, add the potatoes, tomatoes, red peppers, capers, garlic, and oregano. Season everything with a bit more salt and pepper to taste, and drizzle with a few more tablespoons of olive oil. Throw into the oven for 45-55 minutes.
