Whisk all of the ingredients together in a mixing bowl and set aside until needed.
In a 2 gallon stock pot over high heat, add the grapeseed oil and the onions, pepper and celery. Cook until the onions become translucent, about 15 minutes. Add the beans, garlic and andouille and cook for 5 more minutes. Remove from the stove and add the thyme, parsley, Cajun spice and the chicken stock. Pour the entire bean mixture into a casserole dish, and stir in the BBQ jelly. Bake for 20 minutes. Remove from the oven and serve.
Serving options: Grated cheese can be added before baking or before serving.
