For the mustard vinaigrette: Add the vinegar, honey, mustard, hot sauce, garlic and lemon juice to a medium mixing bowl. Whisk constantly while slowly adding the vegetable oil. Whisk until fully combined. Taste the vinaigrette and season with salt and black pepper.
For the sausage and peppers: Bring a medium pot of lightly salted water to a boil. Add the potatoes and sweet potatoes and boil until they are almost cooked, but still raw in the center, about 5 minutes. Drain and cool them completely until ready to grill.
Preheat a char-grill to medium-high heat
Combine the potatoes, sausages, oil, grill seasoning and bell peppers in a large bowl. Toss carefully until well coated. Grill the sausages, peppers and potatoes until char marks have formed and everything is completely heated through, about 6 minutes.
Remove and arrange on a platter. Drizzle with some of the mustard vinaigrette. Serve extra vinaigrette on the side.
To serve, garnish with scallions, parsley and fresh herbs. Serve warm.
