Avocado Spread Sandwiches with Tomato and Radish

Open-faced avocado sandwiches need a ripe avocado and bread with enough structure to hold the topping. Lemon seasons the mash and helps it keep its colour for a short time. Radish adds a sharper crunch beside the juicy tomato. This version keeps the toppings simple and includes no egg, making it a straightforward plant-based lunch or snack when the bread is suitable. Toast the bread before mashing so the avocado can go directly from bowl to plate.
