Salad with mango and avocado

Here is a recipe for a mango salad that I really like. It takes just a few minutes to make, but is very tasty. If you use the amounts of ingredients written below, it will be enough to feed 5-6 people.

Ingredients:

1.5 head of lettuce, chopped
1 mango, chopped
8 cherry tomatoes, cut into eights
1 cucumber, chopped
1 large medium-ripe avocado, chopped
juice of 2 lemons
3 tbsp chopped cilantro
5 tbsp sunflower seeds (roasted or not, whatever you prefer)
salt, pepper

I like to make this salad just before I eat it and I do not mix it till the last moment before eating:
