Prep snow peas by removing the tips and pulling to remove the vein from the side.
Heat a large frying pan on high. When pan is hot, add in oil. Add in garlic and ginger. Saute for 1 minute. Then add in snow peas and tofu puffs. Stir fry for 1 minute.
Add in water to the snow peas, then cover with a lid. Allow to steam for 1 minute. Then add in oyster sauce. Continue to stir fry until sauce is well incorporated into the snow peas, about 1 minute.
Remove immediately from the pan and serve. Snow peas should still retain a crunch.
