Mix the pumpkin with the rice while mashing the pumpkin. Beat the egg and knead into the pumpkin-rice mixture. Knead in the flour - enough so that the dough is slightly dry and has a light bond. Season the dough to taste, add seasoning if necessary
Line the baking tray / rack with parchment paper. Shape the dough into small balls and place them on the baking sheet, flattening the balls a bit. Bake at 200 degrees fan-assisted for between 20 and 30 minutes until the buffers have hardened and have a slightly browned edge
Meanwhile, make a salad from lettuce hearts, tomatoes, cucumber, onions and peppers. Mix a dressing of sorrel pesto, lemon juice and olive oil.
Arrange the lettuce and rice pumpkin pancakes on plates. The buffers taste warm or cold.
