Have you tried the cauliflower in salad? It's great with mayonnaise and boiled potato, you'll see.
The important thing is to cook the potato and cauliflower in advance, so that at meal time these ingredients are very cold. To the salad we will also put some olives and a can of canned corn and peas.
you can prepare the mayonnaise at home or use the purchased one. If you make it at home, do not forget to always keep it in the fridge, as it is very hot and you have to be careful.
