Peanut Butter & Banana Sandwich – £0.32 per serving

A classic that never goes out of style. The combination of protein, fibre and potassium keeps little ones full until the next meal.

Tip: Slice the banana into rings and place them on the bread before adding peanut butter. This keeps the banana from turning brown and adds a fun visual element.

Step‑by‑step:

1. Lay the two slices of bread on a clean surface.
2. Spread a tablespoon of peanut butter on one slice.
3. Arrange banana rings on top.
4. Drizzle a half‑teaspoon of honey if your child likes a touch of sweetness.
5. Cover with the second slice, press gently, and cut into halves or quarters.
6. Pack with a small container of carrot sticks or a fruit cup for extra crunch.

Storage note: Cool the sandwich to room temperature before packing. If you’re packing it for later, keep it in a sealed bag in the fridge and eat within 48 hrs. Reheat only if you prefer a warm bite – use a microwave for 30 seconds, ensuring it’s steaming hot throughout.

Cheesy Veggie Wrap – £0.45 per serving

A quick, portable wrap that turns ordinary vegetables into a delicious, cheesy treat. Perfect for a lunchbox that’s both colourful and balanced.

Step‑by‑step:

1. Lay the tortilla flat and spread hummus evenly across the surface.
2. Sprinkle shredded cheese over the hummus.
3. Arrange salad leaves, tomato and cucumber on top.
4. Roll the tortilla tightly, tucking in the ends.

6. Pair with a small yoghurt cup or a handful of raisins.

Storage note: Wrap the finished product in cling film and store in the fridge. Eat within 48 hrs. If you prefer a warm wrap, microwave for 20 seconds, but be sure it’s steaming hot throughout before serving.

1. Cook the pasta according to the packet, drain and rinse with cold water.
2. In a bowl, mix mayonnaise, tuna, peas and shredded carrot.
