Toss beet chunks with one tablespoon of olive oil. Spread evenly onto prepared baking sheet and roast in oven for 20-30 minutes, or until fork tender. Let cool for 5-10 minutes.
Combine roasted beets and all other ingredients in a large food processor and blend until smooth, about 2 minutes. Scrape the sides of the food processor and blend for another minute, or until smooth.
Serve with apple slices, pretzels, pita chips, naan, etc!
Notes
You can use honey or your other favorite liquid sweetener instead of agave nectar, if desired. Just note that depending on which sweetener you pick, the recipe may not be vegan anymore.
You can use bottled lemon juice instead of fresh, if desired. One lemon yields about 2 tbsp of juice.
