it’s very easy to make! just boil some pasta, make all other ingredients hot and then combine them! i love beige slop. “all other ingredients” are: garlic, vegan gyros from lidl and feta cheese (any simulacrum with “greek type cheese” in the name will work too)
Most industrial made ones don’t actually. Fresh pasta is more common to have eggs, and there’s also specific pastas that will almost always have eggs such as tagliatelle.
