Add a few tablespoons of olive oil to a saucepan over low heat. Add the diced bell pepper and onion, saute until the onion is translucent. Add the tomato paste and chicken, bringing mixture to a boil. Reduce heat and simmer uncovered for 10 minutes. Add peas, and cook uncovered for 5 minutes. Mix in a dash of salt and red pepper, remove from heat and set aside.
