This delicious lentil and black bean burger comes with a little extra of everything. It’s stuffed with roasted nuts, Parmesan cheese, hot chili sauce, and sweetness from balsamic vinegar. I made this recipe for a relative who loves hamburgers and he loved this veggie burger so much he asked for the recipe! Truffle mayonnaise adds an extra layer of deliciousness to this royal veggie burger.
