In a small mixing bowl, combine flour, salt, and pepper. Dredge the chicken thighs in the mixture and set aside.
Heat butter and olive oil in a large skillet over medium-high heat. Add the chicken and fry 5-7 minutes on each side, until golden brown. Once browned, remove from skillet and set aside.
To the same skillet, add onion, peppers, tomatoes, garlic and fresh herbs. Season lightly with salt and pepper and saute over medium heat for 10-12 minutes.
Push the veggies to the outer edges of the pan and add the tomato paste to the center. Cook, stirring, until heated and bubbly (about 2 minutes). Increase the temperature to medium-high, add the wine, and stir. Cook 3-5 minutes, until wine is nearly gone.
Add the crushed tomatoes, tomato sauce, and remaining 1 teaspoon of salt. Add the chicken back to the skillet and bring the sauce to a gentle boil. Once boiling, reduce to a simmer and cover with a lid. Simmer for 45 minutes.
Add capers and garnish with Parmesan cheese as desired. Serve with noodles.
