I've been working on this recipe for a while to come up with what I think is a great meat-free hot dog alternative, all made in just one pan. These dogs are so easy and packed with flavors such as smoked paprika, miso paste and sweet red pepper. Perfect stuffed into a bun and topped with your favorite condiments. Delicious!
For the sausages: Heat 1 tablespoon of the oil in a medium-large saute pan over medium heat and saute the onions and peppers gently, about 1 minute. Stir in the garlic and cook until tender, about 3 minutes more. Stir in the herbs, tomatoes, miso and paprika and cook until the mixture is golden and caramelized, about 2 minutes. Add the beans and heat through, about 1 minute. Turn off the heat, then mix in the flour and flaxseed if using.
Using a potato masher, press the mixture together (you want to retain some of the texture as it adds bite when eating, so be mindful not to over-mash). Using clean hands, bring all the ingredients together firmly and shape into a large ball, then cut into 4 equal pieces. Roll each piece into a long sausage shape. I like to measure each sausage piece up against a hot dog bun to shape them to the perfect length to fit.
Chill in the fridge to allow the sausage to firm up before frying, at least 30 minutes.
Heat the remaining 2 tablespoons oil in a medium-large saute pan over medium heat, then fry the sausages, turning occasionally until crispy and browned, 8 to 10 minutes. Set aside.
For the caramelized onions: Heat the oil in a medium-large saute pan over medium heat, then add the onions and stir in the vinegar. Cook on a gently sizzling heat, stirring occasionally, until soft and caramelized, 8 to 10 minutes.
For assembly: Spread a layer of mayonnaise on the inside of each hot dog bun, then scatter some arugula over the mayonnaise. Add a sausage and spoon some of the caramelized onions over the top. Finish with a squeeze of ketchup and mustard to taste. Now your Smokey Dogs are ready to devour.
If you want to make the smokey sausages ahead, you can shape and store them in the fridge to chill until you are ready to cook.
