Avocados are costly here in Scotland, too costly to waste. This is my way of using three ingredients that "don't float my boat" so to speak, but I really do enjoy one of these with a bit of salad on the side. Maybe a few crisps and a pickle .........well, it depends on how hungry I am. If you are wondering why I said 3 ingredients, I'm not a lover of rye bread.
Avocado and Marmite Sandwich (for one), just multiply as you require.
