Bring a large pot of salted water to a boil. Add spaghetti and cook according to package instructions, about 8-10 minutes, until al dente. Drain and rinse under cold water.

In a medium bowl, combine olive oil, lemon juice, honey, and Italian seasoning. Whisk until well blended and season with salt and pepper.

In a large mixing bowl, add halved cherry tomatoes, sliced cucumbers, chopped red onion, and black and green olives. Drizzle dressing over vegetables and gently toss.

Add cooled spaghetti and crumbled feta to the vegetable mixture and toss to combine.

Taste and adjust seasoning with salt, pepper, or lemon juice as needed. Let sit for 15 minutes before serving.
