Staple Summer Salad

This salad is the perfect accent piece to any summer meal.  It's fast, and last-minute, and easy, (and wont heat up your already hot summer kitchen!).  There are various versions of this salad, but this is the one that I've been making lately.  It feels very nostalgic & comfortable.  Do you have a salad like this in your rotation?
Ingredients:
1 cup English cucumber, diced
2 cups multi-colored cherry tomatoes, quartered 
3/4 cup sharp cheddar, cubed
1 tsp dijon mustard
2-3 tbs apple cider vinegar
1/4 tsp coconut sugar
1 tsp EVOO
sea salt & pepper, to taste

Directions:
1. Chop everything & gently mix in a bowl.  Be careful not to break the tomatoes.  Cover with saran wrap and place in the refrigerator for an hour or so.  Then serve cold.
2. Enjoy!
