Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
Toss diced turnips in olive oil, salt and pepper, and spread on sheet. Bake for 20-30 minutes or until tender and slightly golden brown.
In a high powered blender or food processor, combine roasted turnips with the remaining ingredients. Blend until smooth, adding more olive oil or water as needed to promote blending. You may also add some more lemon juice if desired.
Serve with fresh vegetables, apples, or pita chips. Enjoy!
