Pour boiling water over the shrimp and leave to soak for 10 minutes. Soak the peppers in cold water. Wash the cabbage leaves and line a serving bowl with them.
In the meantime, cap the papaya at both ends, peel, core and grate into strips with a medium-fine grater. Wash the tomato and cut in half. Remove the white-green stem. Cap the onions and garlic cloves at both ends, peel and cut into small cubes.
Strain the shrimp and peppers and drain well. Put together with the onions, garlic and peanuts in a cutter and coarsely puree by pulsing. Put the puree in a bowl. Add the papaya strips in portions and press carefully with a pestle, turning frequently. Add the tomato pieces and also squeeze gently.
Mix in the fish sauce, sugar and lime juice. Season the salad with salt and black pepper, fresh from the mill, to taste and place on the cabbage leaves, serve as a starter and enjoy.
