Potato and Sage Flat Omelet with Russian Dressing

Flat omelets (Italian frittata) are an easy snack since they take only a few minutes and are best eaten at room temperature, making them perfect for taking on picnics or cooking in advance and leaving until needed (as long as they have no shellfish in them).

They don’t need saucing at all, just a little olive oil and lemon, but the Russian dressing is pretty spectacular with this omelet. If you don’t have the caviar, use the tomato and olive oil
