Wash the cucumbers and sweet bell peppers under cold water. Slice the cucumbers into thin rounds and cut the sweet peppers into strips. Place in a large mixing bowl.

In a small bowl, combine olive oil, apple cider vinegar, lemon juice, and honey. Whisk until smooth to create the dressing.

Add the cucumbers, sweet peppers, and thinly sliced red onion to the mixing bowl. Pour the dressing over and gently toss.

Sprinkle chopped fresh dill over the salad and toss once more to mix it evenly.

Cover the salad and refrigerate for at least 15 minutes before serving.
