Why Citrus Breakfast Toast could boost your immunity

Citrus: Citrus fruit contain high levels of Vitamin C, an essential vitamin that supports the immune system and serves as an antioxidant.

Sunflower Seeds: Sunflower seeds contain Vitamin E, a fat-soluble vitamin that acts as an antioxidant, and zinc. Both work to boost your immune system.

California Prunes: Prunes are a great source of antioxidants, which help your body to fight off infections.

What ingredients do you need to make Citrus Breakfast Toast?

For the Brûléed Citrus Wheels:

  • Place the citrus wheels on a heat-proof surface (like a baking sheet) and add a small amount of sugar to the top of each piece.
  • Using a circular motion, pass the flame of a culinary torch repeatedly over the sugar until it boils and turns lightly charred and amber.

To build the toast:

  • Spread 2 tablespoons of sunflower butter on each warm piece of whole-grain toasted sourdough bread. Top with 1 tablespoon prune puree, spread evenly across the sunflower butter. Sprinkle half of the diced prunes and sunflower seeds over top. Arrange half the broiled citrus on top and serve immediately.
