Wash the fruit and vegetables.

Squeeze the juice out of the lemon. Set aside.

Slice the apple into bite sized pieces, then let the pieces soak in the lemon juice.

Slice the orange into 8 slices. Remove the flesh from the skin, then cut each slice into bite sized pieces.

Slice each tomato into four slices. Removing the seeds, slice also into bite sized pieces.

Tear of the lettuce leaves from the head, then slice each leaf into bite sized pieces with a plastic knife.

Put all the ingredients into a bowl (drain the lemon juice from the apple), toss them together, then top with cheese and croutons.

Enjoy!
