It’s summer time, so bring on the burgers.  This is one of my favorite burgers that I have made so far this year.  Ground meat is mixed with sautéed onions, garlic and baby spinach, then topped with a Ricotta cheese sauce and additional fresh baby spinach.  This burger is sure to make your mouth water.  The bread I used was a flat onion and poppy-seed italian bread.  NOTE: This burger can be made with Vegan meat or tuna.  I hope you enjoy!!
