Avocado Sandwich

Name: Avocado Sandwich
Prep time: 8 min
Total time: 8 min
Yield: 2 servings
Cuisine: International
Ingredients: 1 ripe avocado (about 200 g); 4 slices whole-wheat or multigrain bread; 1 medium tomato, sliced 5 mm thick; ½ cucumber, sliced thin; 4 large lettuce leaves; 2 teaspoons lemon juice; ½ teaspoon fine salt; ¼ teaspoon black pepper; 2 teaspoons olive oil or 2 tablespoons hung curd

Most avocado sandwiches fail three hours later, in a lunchbox, when the tomato has soaked the bread. The order of assembly below fixes that.

It is a cold sandwich, no cooking at all, and it takes about eight minutes for two.

Ingredients

Instructions

1
Lay the tomato slices on kitchen paper and sprinkle with a pinch of the salt. Leave for 5 minutes while you do everything else — this draws out the water that would otherwise end up in the bread.
2
Mash the avocado with the lemon juice, remaining salt and pepper.
3
Brush all four bread slices with the olive oil, or spread thinly with hung curd. This is the waterproof layer.
4
Spread the avocado thickly on two slices, then add lettuce, patted-dry tomato and cucumber in that order.
5
Top with the remaining slices, press gently, and cut in half. Wrap tightly in paper if it is going into a bag.

Recipe tips

Lettuce goes directly against the avocado, not against the bread — it acts as a second barrier under the tomato.
Salting and draining the tomato takes five minutes and is the single biggest difference between a good and a soggy sandwich.
Wrap in greaseproof paper rather than a box if you can. A sealed box traps steam and softens the crust.
For a heartier version, add a boiled egg sliced thin or 40 g of grated cheese, both of which sit well against the avocado.

Storage

Best within four hours of making, kept cool. Assembled sandwiches do not survive overnight; prepare the components separately and build in the morning.

Frequently asked questions

How do I keep the avocado from browning in a lunchbox?

Mix lemon juice into the mash and enclose it fully between bread and lettuce. Exposure to air, not time, is what darkens it.

Can I make this the night before?

Not assembled. Mash the avocado with the lemon juice and refrigerate it with film pressed onto the surface, slice the vegetables, and build the sandwich in the morning in about two minutes.

Which bread holds up best?

A dense multigrain or whole-wheat loaf. Soft white bread has no structure and collapses under wet fillings.
