Generate a close-up image of a freshly grilled hot dog nestled in a perfectly toasted bun. The hot dog is topped with a generous drizzle of yellow mustard, ketchup, chopped onions, and pickled jalapeños. The bun is soft, golden brown, and slightly warm. The background includes a blurred dish of golden, creamy macaroni and cheese, giving a comfort-food vibe. The lighting emphasizes the textures, making the hot dog appear juicy and the toppings vibrant.
