What toppings are included on the Roadkill dish?

The Roadkill dish at Texas Roadhouse features a hearty portion of chopped steak topped with sautéed mushrooms and onions. This combination not only enhances the flavor profile of the dish, making it savory and satisfying, but also complements the juicy steak. The sautéed mushrooms add an earthy richness, while the onions contribute a sweet and slightly tangy note, harmonizing beautifully with the meat.

The other options might offer appealing toppings, but they do not reflect what is specifically included in the Roadkill dish. For instance, grilled onions and barbecue sauce could be tasty, yet they do not match the actual ingredients described for this item. Similarly, fried pickles and jalapeños or blue cheese and bacon bits provide different flavor experiences but are not part of the Roadkill topping selection. Thus, sautéed mushrooms and onions are the definitive toppings for this particular dish, making it the correct answer.
