This is my favourite quick salad and it doesn't matter if it gets jumbled around in your school bag as it still tastes great!
lettuce sliced ham cheese cottage cheese cherry tomatoes
1: Get a seal-able tub and put lettuce in it. 2: Add sliced ham. 3: Grate some cheese and put that in too. 4: Add a few tablespoons of cottage cheese. 5: Throw in some whole cherry tomatoes.
For some extra taste, try adding chicken or turkey to the salad and a tasty sauce such as salad cream or sour cream.
