I'm a HUGE fan of mushrooms, as is my little boy. So tonight we topped the burgers off with sweet carmelized onions, golden brown mushrooms and ooey-gooey American cheese (my hubby's cheese of choice on hamburgers). For the buns we used pan de sal, a Filipino dinner roll that is puffy and soft, yet crisp on the outside. The earthiness of the mushrooms went beautifully with the juicy beef. Phenomenal!
