Preheat oven to 400°
On a medium-size foil sheet, add the beets and drizzle a dash of olive oil. Wrap it tightly and place them in a small baking dish filled with a little water. Roast for about 45 minutes to an hour depending on the size of the beets.
Meanwhile, make the WHIPPED FETA. Place all the ingredients to the feta by placing them all in a food processor. Blend well and set aside in the refrigerator until ready to use.
Once beets are cooled, use the foil to wipe the skin off the beets. Dice up the beets and place them in a large bowl.
Add the sliced fennel, lime juice, salt, pepper, olive oil, mint, and pistachios. Mix well and adjust seasoning as needed.
To serve, scoop the whipped feta on a plate and top with the beet and fennel salad. Garnish with fennel fronds and mint.
