Avoiding meat, dairy and eggs isn’t hard. You just do it. I’ve managed to go two years without eating any meat and, besides some of the social implications, it wasn’t hard to do. I just ate something that didn’t contain animal flesh. Same thing with avoiding dairy and eggs for the past six months. I just ate something that didn’t contain animal byproducts. It’s not really that fancy. I don’t have to make really fancy dishes (though sometimes I like the challenge).
