For the BBQ sauce: Combine all of the sauce ingredients in a stockpot or large Dutch oven. Bring to a boil over high heat, stirring frequently to prevent sticking. Reduce temperature to low and simmer- uncovered, for at least 2 hours
For the spaghetti: Dice bell peppers and onions and saute together in extra-virgin olive oil. Add the sauteed vegetables and cooked pork to the sauce and continue to simmer for up to 1 hour. Cook pasta according to package directions and drain. Pour sauce over cooked pasta and serve.
