Step-by-Step Cooking Instructions

Step 1: Pre-Bake the Peppers (for Better Texture)

• - Preheat the oven to 200°C (392°F).
• - Slice each bell pepper in half vertically, cutting straight through the core.
• - Use a spoon to scoop out any seeds and membranes.

Step 3: Assemble & Bake

• - Spoon the filling generously into each pre-baked bell pepper half, filling to the top.
