Ingredients for 2 servings

2 servings

Check off ingredients as you go.

Contains gluten, milk. Check the labels on packaged ingredients:

  • mozzarella. Some mozzarella is made with animal rennet; check the label if you are vegetarian.
  • bread rolls. Rolls often contain soya and can contain milk, egg or sesame; check the label.
  • black olives. Olives are packed in brine and are salty; rinsing removes some of it.

Cooking steps

  1. Slice the tomatoes about 5 mm thick, lay them out on kitchen paper and leave them for 5 minutes to give up their water.

  2. Drain the mozzarella well and slice it the same thickness.

  3. Split the bread rolls and layer in the tomato first, then the mozzarella, then the halved olives.

  4. Tear the basil over, drizzle with the oil and close the rolls, pressing them gently so everything settles.

The useful detail

Drain the sliced tomato on paper before it goes anywhere near the bread. Straight off the board it carries enough water to soak through the base within minutes, and a wet roll cannot be saved.

Make it work for you

One serving is One filled roll. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Feta instead of mozzarella

    Much saltier and firmer; use less, and leave out the olives.

    Per serving: about 5 kcal more, about 6 g less protein, about 3 g more fat.

  • Sourdough instead of rolls

    Chewier and it holds the filling better as an open sandwich.

    Per serving: about the same energy, about 2 g more protein, about 3 g less fat.

  • Leave out the olives

    Cleaner and less salty, and it lets the tomato come through.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A twelve minute lunch where a ball of mozzarella across two rolls carries most of the protein, without any cooking at all.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 2. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Best made and eaten at once; the bread softens within a couple of hours. Keep the components separately for 3 to 4 days.
Reheating
Not needed; this is a cold sandwich.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
