Real wontons and wonton soup are never vegan. Wonton wrappers contain egg by default, at which point they're typically stuffed with meat and served in meat stock or broth. Fried wontons (the appetizer) are usually filled with meat (beef, crab, etc.), and/or cream cheese.

Are wontons vegan?

Generally speaking, no, wontons aren't suitable for vegans. This isn't to say that there aren't many delicious plant-based wonton recipes and restaurants, but they're most likely to include egg in the dough and quite often meat in the filling.

What are wontons typically made of?

Wontons are made by spreading a square wrapper (a dough skin made of flour, egg, water, and salt) flat in the palm of one's hand, placing a small amount of filling in the center, and sealing the wonton into the desired shape by compressing the wrapper's edges together with the fingers.
