I used three one cup ramekins to make these. Spray each ramekin with the butter spray. Saute the onions in the olive oil until golden brown then add the chopped broccoli florets,sliced mushrooms until just tender,season with salt and pepper then set to the side to cool.Combine the eggs,baking powder and half and half,mix them well.
Divide the broccoli mixture between the three ramekins and distribute the egg mixture between them then top with cheddar and grated cheese.
Bake in your pre-heated toaster oven at 350 degrees for 20-25 minutes or until a toothpick inserted in the middle comes out clean,enjoy!
