As someone who knows his ways around the kitchen: No. It is definitely not easy, even if you just go for the salad option. Have you ever looked at any ingredient list? Some store-bought “fresh” pasta is not vegan. A lot of things you would not think for a second about them containing animal products like salad dressings are actually not vegan. In a lot of countries, McDonalds fries are not vegan.
And as soon as it comes to the necessity to replace non-vegan ingredients with vegan ones, you’ll fall down a rabbit hole of “this can be used to replace that, but only in those circumstances”, “Yes, you can replace X with Y, but you have to be careful to cover up some flavors”, or even “The replacement for X is basically a doctoral thesis in chemsitry”.
