Cost: $15.65 total, $15.65 per serving

Ingredients

  • 2 slices Butterfly Pea Flower Sourdough Bread (fresh, thick‑cut; the blue color comes from baked butterfly pea flowers)
  • 2 oz Cheddar Cheese (shredded or thinly sliced; melts well)
  • 1 tbsp Unsalted Butter (softened for easy spreading)
  • 1 tsp Lemon Juice (freshly squeezed; provides the acid that triggers the color change)
  • 1 pinch Salt (enhances flavor of the cheese)

    Time: PT4M

    Temperature: 350°F
