What's more basic than burgers at the all-American cookout? Fortunately there are several varieties to choose from. Leading the pack is Boca brand but there are numerous other brands. If you're interested in getting a burger that looks like a traditional burger you should check out the Boca Burgers, the Vegan Original. They even have grill lines!! I can't vouch for the taste as I haven't tried them but Denise seem to enjoy them very much.
Cooking Veggie Burgers:
The first question I get when I bring the veggie burgers out to the grill is "How do I cook these?" To which I answer "Just like any other burger." Veggie burgers are pretty much already cooked straight out of the package and pretty much just need to be heated up.
The next question is "How do I tell when it's done?" That's a tricky one. Veggie burgers don't really change colors or have juices that run clear when it's done. When the burger is nice and hot all the way through, you can declare the burger done. You can tell that by either using one of those ultra-cool termo-forks (just like I don't have, humpf!) to tell how hot the middle is or I just use a fork. Since the burgers are usually cooked straight out of the freezer so one they're soft enough for a fork to poke through it easily I consider it done.
Once the burger is cooked the actual condiment application is usually best left to the individual user.
