Mix everything in a medium sized bowl and let sit for 5-10 minutes to let the breadcrumbs absorb some of the moisture.  You can even mix this in the morning and cover the bowl in the fridge until later.  Once ready, spritz a skillet with oil and heat over medium.  I found my batter was too sloppy to form with my hands so I dropped large spoonfuls onto my pan and spread out into a round shape with my my spoon which worked perfectly, and they held together great.  The burgers should be no thicker than 3/4".  Cook over medium(or slightly lower) heat until the bottom is golden then gently flip the burger over and cook the other side until golden.  Serve hot on a bun with your favorite condiments or on a bed of greens.
