Step 1

Toast the sandwich buns either in your skillet or over a grill. Set aside.

Step 2

Heat half the butter or oil in your skillet over medium high heat. Once melted, add the cheese. Fry on each side until golden brown in spots, about 3-4 minutes per side. Set aside. This step could also be done on a grill if you have one going. In that case, skip the butter/oil, and place the cheese directly on the grill.

Step 3

Heat the remaining butter or oil over medium heat. Once melted, crack the egg into the skillet. Totally optional step: Once the whites begin to set, you can use a fork to mix up the yolk a bit so that it gets distributed throughout the egg a bit, so there will be yolk in every bite. Cook the egg for about 4 minutes, or until they are cooked to your preferred doneness.

Step 4

While the egg is cooking, prep the spicy mayo. In a small bowl (or in a measuring cup), mix together the mayo and the Sriracha.

Step 5

To assemble, spread the spicy mayo on each cut surface of the buns. Layer on the grilled halloumi, egg, scallions, and salt & pepper to taste.
