I have tried every brand of vegan and vegetarian burger substitutes out there at this point and I can safely say that Quorn is by far the best Children are more likely to get lice than adults.. They make a “hot and spicy” vegan patty which is to-die-for and is delicious with some ketchup and mustard between a gluten-free bun. Made from mycoproteins, this chicken substitute is more convincing as a meat analog than any other product out there at the moment.
