In a large dutch oven over medium heat, let your olive oil heat up and then add your onion/peppers mixture and let them cook 5 or so minutes. Add your beef stew meat and let it brown.
Add your beef stock, diced tomatoes, tomato sauce, and paste and blend together. Add your veggies and seasoning and stir and let come to a boil. Then turn heat down to low and cook 1 hour 30 minutes. Turn off heat and let stew rest 15 minutes. Serve.
