Lentil Salad

Here is one of my all time favorite side dish/ snack/ all around good food recipes. It is deceptively easy and tastes so freaking good.
Ingredients:
1 1/4 cups brown lentils, rinsed
1/4 cup red wine vinegar
3 tablespoons olive oil
1 large cucumber, peeled and diced
1/2 cup finely chopped fresh parsley
1/2 cup finely chopped red onion
salt and pepper
Directions:
1 - In a small saucepan, cover lentils with water by one inch. Bring to a boil. Reduce heat and simmer, partially uncovered, until lentils are tender but still holding their shape. (20 to 25 minutes) Drain well.
3 - In a large bowl, whisk together vinegar and oil. Add lentils, cucumber, parsley and onion. Season with salt and pepper. Toss well to coat with dressing.
4 - Cool to room temperature or serve chilled
