As a dedicated reader may have noticed, Ben is a rather prolific carnivore. In fact, in the words of one critic, he is our generation’s Mark Bittman. I tend to lean a bit more vegetarian, and so I often try to replicate recipes like Ben’s, but with vegetable substitutes.
A few weeks ago, my wife and I made delicious portabello burgers in our panini press. It’s really super-simple.
1. Let the portabellos sit in the marinade of your choice for about twenty minutes. We used barbeque sauce, but almost anything will work – teriyaki sauce, olive oil, beer, etc.
2. Grill them in the panini press for about 3-5 minutes per side, until you see nice, meat-like grill marks.
3. Throw them on a toasted bun, with lettuce or tomatoes. You can also make a delicious greek yogurt and avocado dip, which nicely complements the burger.
4. Take pictures of your creation. Blog about it. Wish you founded Whole Foods. Repeat.
