Pulse oats in food processor until oats are broken down, but not as fine as flour. Set mixture aside.

Using 1/2 cup measure Patty burgers and place on large baking sheet. Grease pan or tray with olive to avoid burgers sticking. Place burgers in fridge to chill, this will help prevent them from falling apart during cooking.
Once chilled, heat large cast iron skillet over medium-high until pan begins to smoke. Add olive oil to pan. Add burger patties to pan and cook for approx. 4 minutes each side.
Add all spices to bowl and whisk together. Set aside.
