Easy Greek Pasta Salad with Homemade Dressing is made with fresh ingredients including tomatoes, cucumbers, onion, olives and feta cheese. It can be made in minutes and is best made ahead!
Add celery (or peppers), olives, cucumber, green onions, and tomatoes to pasta in large bowl. Set aside 1/2 to 1 cup of this mixture for topping salad.
In a small bowl, whisk together dressing ingredients. If using bottled dressing, whisk dressing, mayo, oregano and pepper. If homemade, place all ingredients in a jar or deep bowl or blender. Use an immersion blender or regular blender to mix dressing. Set in fridge until ready to use.
Fold dressing and cheeses into pasta and vegetable mixture.
Add tomatoes, folding in gently.
Sprinkle reserved feta and a few reserved vegetables on top of salad before serving.
