Vegenaise is one. Morningstar Farms Chipotle Black Bean Burgers are another.
There are a few inherent problems with veggie burgers. Homemade ones can taste great, but they tend to be too soft to grill, so they can't provide the full burger experience. Processed burgers, on the other hand, too often are dry, bready, and tasteless.
But Morningstar Farms' chipotle-spiked black bean burgers grill beautifully, developing a "meaty" crust that could satisfy the most bloodthirsty carnivore. They're firm, flavorful, and, at a quarter pound apiece, satisfyingly large. They are heaven.
We discovered them at Costco, promptly finished a box, then went back for more, with some trepidation; Costco has a habit of dropping products that don't quickly catch on. Up and down the frozen aisle we prowled, worried that we'd never see the burgers again at a Costco price. Nothing . . . until we turned a corner and saw that Costco had devoted the entire "end cap" of its freezer section to a gigantic display of the burgers! As Costco is hardly a vegetarian paradise, we have to assume that this product is catching on with everybody.
Try them! You may never go back to hamburgers.
