We have a few available in the US, my favorite is https://en.wikipedia.org/wiki/Quorn#Production which is not vegan as it contains some amount of egg. But the majority of the product is made from soil mold protein, which is what makes it unique among the options I have available.
Ah, you have Quorn as well? Back when there was not that much choice in the Netherlands, Quorn was one of the few brands that was available. It doesn't taste as good as most others in my opinion, though, and also has the disadvantage of not having added some nutrients that vegans and vegetarians often miss out on.
In the US, based on personal experience, I'd recommend Morningstar Farms for their variety, Beyond Meat if you can find it, and Field Roast Grain Meat.
