Ingredients
  

  • 8 oz spaghetti pasta
  • 1 cup cherry or grape tomatoes halved
  • 1 cup cucumber diced
  • ½ cup red onion thinly sliced
  • 1 cup sliced pepperoni
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons fresh parsley chopped
  • For the Vinaigrette:
  • ¼ cup olive oil
  • 2 tablespoons red wine vinegar
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried oregano
  • 1 teaspoon garlic powder
  • Salt and pepper to taste

Instructions
 

  • Cook the Pasta: Boil the spaghetti according to package instructions until al dente. Drain and rinse under cold water to stop the cooking and cool the noodles.
  • Combine Ingredients: In a large bowl, mix the cooked spaghetti, halved tomatoes, diced cucumber, sliced red onion, and pepperoni.
  • Make the Vinaigrette: In a small bowl, whisk together olive oil, red wine vinegar, Dijon mustard, oregano, garlic powder, salt, and pepper.
  • Dress the Salad: Pour the vinaigrette over the pasta mixture and toss until everything is evenly coated.
  • Finish and Chill: Sprinkle with Parmesan cheese and chopped parsley. Cover and refrigerate for at least 1 hour before serving for best flavor.

Notes

  • Use mini mozzarella balls or cubes of cheese instead of Parmesan for a twist.
  • Add olives or bell peppers for extra crunch and color.
  • Great for meal prep—flavors develop even more after a day in the fridge.
  • Use whole wheat or gluten-free pasta if preferred.
