2 Prep the veggies: Finely mince the broccoli and mushrooms.
3 Mix it up: In a large bowl, whisk the eggs. Add flour, cheese, baking powder (if using), salt, garlic powder, and herbs. Stir until combined.
4 Fold in the veggies until evenly distributed.
5 Bake: Pour into the prepared dish and bake for 20–22 minutes, or until the edges are golden and the center is set.
6 Cool and slice: Let cool before cutting into squares. Store in the fridge for up to 4 days or freeze for later.
