Place the yogurt in a small bowl and add a few drops of yellow food colouring. Stir well to combine until the yogurt is bright yellow - you may need to add a little more food colouring to get the desired shade.

Drop spoonfuls of yogurt into a 6 hole silicone muffin tin, dividing it equally between the sections. If you don't have a silicone muffin tin, try using silicone cupcake or muffin cases instead.

Tap the muffin tin on your worktop to level the yogurt.

Cut slices from the strawberries, then cut mini hearts from the strawberry slices, using a mini bento cutter.

Cut mouth shapes from the dried fruit roll-up using a small round cutter or by hand.

Carefully place 2 hearts and a dried fruit 'mouth' into each section of the muffin tin, taking care not to push them too far into the yogurt.

Place the muffin tin in the freezer and leave to freeze for a couple of hours until set solid.

Once frozen through, pop the yogurt bites out of the muffin tin and serve.
