This delicious potato salad was inspired by a recipe handed down from my great grandparents, who lived in a small town near Sevilla, Spain. It was originally made with green olives and served at a local pub as "tapas" (appetizer). I updated the recipe with my own twist, sauteing capers in olive oil until crisp in place of the olives. I love the combination of smoky flavors and the tangy mustard dressing!
1In a large pot, add potatoes and 1 tablespoon kosher salt. Cover potatoes with water by about 1 inch. Bring to a boil, over medium high heat. Reduce to simmer; cover. Cook, about 18-20 minutes, or until fork tender. Drain. Transfer to a large bowl; let potatoes cool slightly.
2Meanwhile, over medium high heat, heat 1 tablespoon olive oil in a large nonstick skillet. Add chorizo; cook chorizo about 8-10 minutes, or until slightly crisped. Transfer to a paper-lined plate. Set aside. Drain drippings in skillet, reserving about 1 tablespoon drippings in skillet. In same skillet, add 4 tablespoons olive oil, garlic, and onions. Cook, stirring, 3-4 minutes or until onions are tender. Add oregano; cook 1 additional minute. Remove from heat. Stir in mustard, honey, vinegar, smoked paprika and red pepper flakes until well combined. Set mustard-onion dressing aside.
3While potatoes are still warm, add crumbled chorizo, red peppers, parsley, eggs, and mustard-onion dressing. Season with kosher salt to taste. Gently stir to mix ingredients.
4In a small skillet, over medium heat, heat remaining 1 tablespoon olive oil. Add capers; cook 1-2 minutes, or until they begin to pop and crisp slightly.
5To serve, spoon potato salad in a large serving bowl; sprinkle with crisped capers. If desired, garnish with parsley sprigs. Serve room temperature.
