Heat a cast iron skillet over medium-high heat.
Place the meat in a bowl and season with salt and pepper. Add the onion, garlic, Worcestershire sauce, Dijon, Sriracha, relish, celery seed, paprika and parsley and mix well. Form four patties and drizzle with oil.
Cook the patties for 8 minutes in the hot pan, turning once. Top with the cheese during the last minute to melt. Serve on the rolls with the lettuce, tomato and onion.
