You can serve this with olive oil and vinegar or with mayonnaise ( see 2 minutes mayonnaise sauce post). If you use mayonnaise then this is called 'little Russian salad' (ensaladilla) in Spanish.
You need:
3 big potatoes diced (small cubes)
3 carrot (also diced into small cubes)
3 hand fulls of frozen peas
4 cornichons (cut into tiny pieces)
8 green olives (also cut into tiny pieces)
4 tinned red peppers (cut into small pieces)
1 tin of tuna (into small flakes)
you can also add if you wish a couple of boiled eggs cut into small cubes ( we did not use them for the picture below)
Boil water in a pan.Using a steamer (we have a stained steel fan, but you can also use a Chinese steamer) steam the potatoes and carrots in salty water for 10 minutes ( you can also just boil them for 7-8 minutes but the texture will not be as nice). Boil the peas for 3-4 minutes. Mix the potatoes, carrots, peas and all the other ingredients. Taste it as you may need to add a bit more salt at the end. You can serve this (with olive oil and vinegar or with mayonnaise) with a simple green salad as a main course for lunch.
