Wash and optionally peel the cucumbers, then dice into bite-sized pieces. Halve the cherry tomatoes and finely chop the red onion. Combine in a large mixing bowl.

Add the diced cucumbers, halved cherry tomatoes, chopped red onion, shredded cheddar cheese, and crumbled bacon to the mixing bowl. Gently mix to combine.

Pour ranch dressing over the mixed ingredients and gently toss with a spatula until all ingredients are coated.

Season with salt and pepper to taste, and toss again. Add fresh dill if using.

Chill in the refrigerator for about 30 minutes before serving for best flavor.
