I would eat these over a beef burger any day.
Its hard to find veggie burgers that actually taste edible, and Kirkland (Costco brand) has perfected them.
They actually don't contain any tofu, their main ingredients are mushrooms, bulgar wheat, rice, feta cheese and a ton of spices. They are incredibly juicy and and a great healthy alternative that actually makes you crave them.
They are a bit tricky to cook, they tend to stick to the BBQ, I often bake mine or pan fry with a bit of olive oil. I garnish with onion, tomato, lettuce and mayo. They keep really well too, I will cook an extra one the night before and reheat at work the next day, they still hold the juice and flavor nicely.
