2 leeks, thinly sliced, white and pale green parts only [you can save the tougher green ends for stock]
1 red bell pepper, thinly sliced
1/4 cup olive oil
2 Tbsp fresh lemon juice
1 Tbsp Dijon mustard
1 Tbsp chopped fresh thyme
1/2 tsp salt
Preheat oven to 400°F. Line a rimmed baking sheet with foil.
Place the cauliflower, leeks, and red pepper on the baking sheet.
In a small bowl, combine the rest of the ingredients. Add to cauliflower mixture, tossing gently to coat.
Bake until tender, 35 to 45 minutes, stirring occasionally. Enjoy!
