In a large skillet, heat oil over medium heat. Add the onions and peppers and saute, stirring occasionally, until they're tender and starting to brown. Add the garlic and saute until fragrant, about 1 minute. Stir in the tomatoes and all the juice, broth, cumin, smoked paprika, oregano, salt, and pepper. Bring the mixture to a simmer then lower heat and continue to simmer uncovered for 20-25 minutes or until the mixture is thickened.
