Place couscous, water, 1 teaspoon kosher salt, and butter, in a microwave safe bowl. Microwave on high (uncovered) for 4 minutes and let sit for one minute. Use a fork to fluff the couscous and set aside.
In a small bowl whisk olive oil, curry powder, and lemon juice with salt and pepper to taste.
To the couscous, add the cucumber, tomatoes, and onions. Pour on the curry dressing and toss to combine. Eat warm or refrigerate for later.

Notes
If making ahead, make sure the couscous is cooled before adding the veggies.
Toss in feta, parsley, garbanzo beans, or any other veggies to change up the flavors of this salad.
This is delicious served with grilled meats and a side of pita bread.
