Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Place 2 halved grapefruits cut side up on a baking sheet, drizzle with 1 tbsp extra virgin olive oil, and roast for 20 minutes until edges caramelize and flesh softens.
  2. Step 2: While grapefruit roasts, whisk together 1/4 cup bitter orange juice, 1 tbsp honey, 1 tsp Dijon mustard, 1/2 tsp salt, 1/4 tsp black pepper, and 2 tbsp extra virgin olive oil in a bowl until emulsified.
  3. Step 3: In a large salad bowl, toss 1 small chopped radicchio with the vinaigrette until evenly coated.
  4. Step 4: Remove grapefruits from oven and allow to cool slightly; segment the flesh by cutting between membranes and add to the radicchio mixture.
  5. Step 5: Sprinkle 1/4 cup chopped toasted walnuts and 1/3 cup crumbled feta cheese over the salad and gently toss just to combine. Serve immediately for a fresh balance of bitter and bright flavors.
