Fancy Beef Burger

In a large bowl, combine all of the ingredients (excluding the garnish ingredients) and mix well. Divide meat into 4 equal portions and start forming them into patties. I do this by using two hands and putting the meat on a sheet of wax paper. I flatten it to about 1 inch thick. Repeat this for remaining burgers. Tightly wrap and refrigerate for at least 1/2 hour before cooking. I do this so the meat stays together better while cooking.

Heat a large skillet over medium to high heat and add a little olive oil to the pan. Add the burgers and cook each side for about 6 minutes. Gently flatten the meat while it is cooking. I like my burgers well done, so if you prefer it less done, don't cook it as long.

Transfer to serving plates and top with tomato, fresh mozzarella and caramelized onions. Add the spinach on the side and drizzle over a little of the balsamic reduction. A great mid week supper that is sure to satisfy.

*Note: To caramelize the onions, heat a medium skillet set over a medium heat. Add olive oil and sliced onions. Cook for about 5-8 minutes until browned. Turn heat to low and continue cooking until onion are completely soft and browned. This will probably take a further 10-15 minutes. Remove from heat.
