Start by caramelizing the onion. Heat the olive oil over medium low heat, and add the onion. Let simmer for 25 minutes, until golden brown.

Meanwhile, heat your oven to 400 degrees. Grease a baking sheet with 1 teaspoon of butter. Then stretch the pizza dough to make a 12 inch round pizza.

Spread the caramelized onions evenly over the pizza dough. Then add the spinach and blue cheese on top.

Place in the oven to bake for 25 minutes.

Next mix the salt, pepper, and garlic powder together creating a seasoning for the steak. Pat the steak dry with a paper towel, and then generously sprinkle the seasoning on the steak.

Heat a grill pan over high heat, add the remaining butter, and once it melts add the steak.

For medium rare steak, cook it for 4 minutes per side, and then let it rest for 5 minutes.

Thinly slice the steak, remove the pizza from the oven, top the pizza with the steak, and drizzle balsamic vinegar over.
