Step 1

Preheat the grill to 300 degrees Fahrenheit. This will ensure that the grill is hot enough to properly cook the picanha steaks.

Step 2

While the grill is preheating, cut the picanha roast into 3 equal size steaks against the grain. This will help to make the steaks more tender and flavorful.

Step 3

Skewer the picanha steaks and season them with salt. The salt will help to enhance the natural flavor of the steak.

Step 4

Once the grill is hot, place the skewered steaks on the grill until they reach an internal temperature of 125 degrees Fahrenheit. This will help to ensure that the steaks are cooked to the desired level of doneness.

Step 5

While the steaks are cooking, prepare the sriracha aioli sauce by combining the mayonnaise, sriracha sauce, and garlic paste in a bowl. Mix well and set aside. The garlic paste will add a delicious depth of flavor to the sauce, while the sriracha sauce will provide a spicy kick.

Step 6

Slice the onion and sauté in a skillet with butter, salt, and pepper until tender. This will help to bring out the natural sweetness of the onion and add an extra layer of flavor to the sandwich.

Step 7

In the same skillet used for the onions, sear the pepper Jack cheese until it melts. This will help to melt the cheese and give it a nice golden brown color.

Step 8

Once the steaks are done, remove them from the grill and let them rest for a few minutes. This will help to ensure that the juices are evenly distributed throughout the meat and make the steak more tender and juicy.

Step 9

Cut the picanha steaks into thin slices while still on the skewers. This will help to make the steak easier to eat and add a nice visual element to the sandwich.

Step 10

To assemble the sandwich, spread the sriracha aioli sauce on the bottom half of each dinner roll. This will help to hold the sandwich together and provide a nice contrast to the flavors of the steak, cheese, and onions.

Step 11

Add the sliced picanha steak on top of the sauce, followed by the sautéed onions and melted cheese. This will help to create a delicious layer of flavors and textures in the sandwich.

Step 12

Place the top half of the dinner roll on the sandwich and enjoy! The combination of the juicy steak, melted cheese, sautéed onions, and spicy sriracha aioli sauce will create a delicious and satisfying meal that is perfect for any occasion.
