The vegan mini sausage rolls from Rotterzwam are made from oyster mushrooms and are delivered pre-baked. This means that only a few minutes of reheating in the oven are needed to serve them. Additionally, the oyster mushrooms are not only known for their savory taste but also for their meaty texture, creating an authentic sausage-like experience without any animal ingredients.

The B Corp-certified Rotterzwam aims for a society that closes loops, optimally utilizes resources, and uses more plant-based than animal proteins. That's why we cultivate our oyster mushrooms on coffee grounds, turning coffee grounds from waste into a valuable resource.

The result includes an extensive range of products and services related to mushroom production, awareness of the circular economy, and fair snacks based on plant-based proteins.
