- 2 bunches new onions (1 inch in diameter), trimmed, or 1/2 pound boiling onions
- 1 pound fresh peas in pods, shucked (1/2 to 1 cup)
- 2 pounds wax beans, trimmed
- 3 ounces Spanish chorizo (cured sausage; 5 inches long),peeled, halved lengthwise, and sliced 1/8 inch thick
- 1/4 cup extra-virgin olive oil
- 1/4 cup Sherry vinegar
- Cut an X in root end of each onion, then cook onions in an 8-qt pot of boiling salted water (2 1/2 tablespoons salt for 5 quart water) until tender, 8 to 10 minutes. Transfer with a slotted spoon to an ice bath to stop cooking (keep pot of water at a boil), then drain onions well. Discard any skins and squeeze onions at stem end so small layers slip out separately.
- Boil peas until just tender, about 2 minutes, cooling and draining in same manner as onions, then wax beans, 4 to 6 minutes. Transfer onions, peas, and beans to a large serving bowl.
- Warm chorizo, oil, and vinegar in a heavy medium skillet over medium-low heat. Remove from heat. Add 1 tsp salt and 1/2 tsp pepper, then pour over vegetables and toss to coat.
