1 lb (500 g) pallares (large dried lima beans)
Water
Salt
1 cup olive oil
2–3 teaspoons white vinegar
1 spoonful Dijon mustard
Pepper
1 red onion, finely diced
2 tomatoes, seeded and diced
A few sprigs of parsley
Soak pallares overnight or at least 6 hours. Change water 2–3 times.
6 hours
Boil the beans without salt in enough water to cover them. Use high heat until water reaches boiling point. Skim and reduce your fire. Simmer for about 1 hour. No exact timing is possible, since cooking time depends on the dryness of the beans.
1 hour
When the beans are plump and tender, take them off the heat and drain. You might reserve the boiling liquid to process leftovers into a soup.
Season the beans lightly with salt (kosher works great) and, while the beans cool down, prepare your vinaigrette.
Mix olive oil, vinegar, mustard, salt and pepper to taste, red onion, and tomatoes.
Once the beans are at room temperature, check the seasoning of the vinaigrette. It should taste a bit stronger than expected.
Carefully mix the vinaigrette with the beans, then mix in the parsley.
Garnish the top with more parsley, and serve.
