Step 1: In a chopper (food processor) puree the onion, garlic and pesto sauce together
Step 2: Make six same size patties out of the hamburger
Step 3: On three of the patties spread on the pesto mixture, spread on a tablespoon of horse radish, sprinkle on the hot spice and season with salt and pepper
Step 4: Top with the remaining three patties and firmly seal the edges.
Step 5: Spray a skillet lightly with oil, turn to high heat. Add the burgers and cook for 1 minute
Step 6: Turn the heat to medium. Flip the burgers, add mushrooms to the pan cover and continue cooking for another 5 minutes, flip the burgers again. You may want to lower the heat further. Continue cooking for approximately another 5 minutes, or until the burgers are done the way you like them. Stir the mushrooms around to evenly brown them.
Step 7: Meanwhile toast one side of your buns, put a slice of cheese on each bun and let it melt under the broiler
Step 8: Assemble your burger by putting on all the condiments that you like. I find to eat this burger cut it in four and it won't all fall in your lap.
