1. Rinse the wild rice under cold water. In a saucepan, combine the wild rice and water. Bring to a boil, then reduce heat, cover, and simmer for about 45 minutes or until the rice is tender and the water is absorbed.
2. While the rice is cooking, prepare the vegetables: halve the cherry tomatoes, dice the cucumber and bell pepper, finely chop the red onion, and chop the parsley.
3. In a large mixing bowl, combine the cooked wild rice, cherry tomatoes, cucumber, bell pepper, red onion, and parsley.
4. In a small bowl, whisk together the olive oil, lemon juice, salt, and black pepper. Pour the dressing over the salad and toss to combine.
5. Serve immediately or refrigerate for up to 2 days.
