Mango Salad with Green Peppers

I usually have something similar to this salad in an Arabic fast food place called Akli

1. One unripe mango
2. Half a green pepper
3. Half a yellow pepper
4. One medium cucumber
5. One medium zuccini
6. One tablespoon lemon juice
7. One tablespoon olive oil
8. Pepper and salt

Chop everything in medium square, combine them in a salad bowl and mix.
