Apparently, this is the salad that Jennifer Aniston ate for lunch on the set of Friends for 10 years! This is my version of her salad. If you want to make my Dijon vinaigrette: 1-2 teaspoons Dijon mustard, 2-3 Tablespoons apple cider vinegar, 1/2 to 3/4 cup good quality olive oil. Salt and pepper to taste. Whisk (or shake), taste and adjust anything as needed. I like to add finely diced shallots as well sometimes. If adding tuna: 1 can of albacore tuna, drained. Mash with a fork. Add some Dijon mustard, olive oil, salt and pepper and capers (as much as you want; start with 1 tablespoon). Mash and mix again. Add to salad. Cook time will vary based on what you use. For the brown rice, I simply microwaved a bag of brown rice and it was ready in 3 minutes. If making quinoa or bulgur, that can take up to 15 minutes.
