Instructions
 

  • Preheat oven to 375°F (190°C), and light a candle for good kitchen energy.

  • Pour mixture into baking dish. Spread it evenly like vegan joy.
  • Sprinkle crispy onions on top for crunch and attitude.
  • Bake for 30 minutes until golden, bubbling, and practically begging for a fork.
  • Let cool for 5 minutes before devouring like no one’s watching (but we know they are).
