From the popular restaurant chain Dinosaur Bar-B-Que, this mother hen of a sauce sure knows how to roost her chicks. It's featured throughout the restaurant's cookbook, Dinosaur Bar-B-Que: An American Roadhouse, and is a classic barbecue sauce that will perfectly douse any dish you're making.
Pour the oil into a large saucepan and set over medium-high heat. Toss in the onions, green peppers, and jalapeños and give them a stir. Season with a pinch of salt and pepper and cook until soft and golden. Add the garlic and cook for 1 minute more. Dump in everything else except the Liquid Smoke. Bring to a boil, and then lower the heat to a simmer. Simmer for 10 minutes. Swirl in the Liquid Smoke and let the sauce cool. Pour it into a container, cover, and store in the fridge til ready to use.
