Pre-ritual diet

[Brass Bell Doll]

Some rituals include diet in the pre-ritual preparations.

What reasons have you seen for this if any?

Also, do you have any vegan dishes you can recommend?

I'm an outsider to ritual, but I would imagine it's similar to the reasons for ritual cleansing? Which, as I understand them, are to purify and to foster a sense of the sacred. Perhaps there is a meaning like the Host in Catholicism, although that's taken during the sacred observation. So perhaps it is transformative, taking a part of a higher being into one's self for the purpose of raising one's consciousness.

Those are both very good reasons.
The adjustment of diet, including intake of certain things or abstention of others can also change our perceptions.

Some foods can also counter act the ritual itself, but most of that seems to deal with energy work in my experience.

Depends on the ritual.
Sometimes I fast, sometimes I eat only meat, sometimes I eat only veg.  

[Deoridhe]

I've never changed my diet, but meat plays a central roll in feasts in Asatru and types of meat are mentioned specifically in the lore.

I've honestly never held to a type of diet long enough to see if it changed anything noticeable in me. I know that if I limit what I consume too much I start to feel edgy and restricted, but that seems to be more emotional than magical.

In my own tradition, there are dietary changes before ritual in order to purify the body, clearing away miasma.

I don't have any dishes, really. When I fast to purify myself, I avoid eating or drinking anything at all except for a very small, but highly nutritious meal a few hours before. I have the feeling that, if it's intrinsically human processes that offend the Gods, then I should definitely not be preoccupied with hunger when I worship nor preoccupied with a meal I just ate. Maybe some lightly steamed asparagus with a slight drizzle of olive oil and some salt and pepper with a big glass of water.

Depends on the ritual.

Quoted for emphasis.

Diet can effect, as previously mentioned:
Your perceptions.
Your body composition.
Your purity in the eyes of certain divinities.
The diet itself may be a part of the ritual.
The diet may involve sacrifice, specified or generalized.
