In a food processor, blend together either raw or thawed from frozen broccoli and cauliflower florets. Pulse and scrape the food processor down with a wooden spoon until you have a consistent mixture of fine, crumbly pieces.
Step 2
At this point, preheat an oven to 350 degrees. In 4-5 additions, squeeze the liquid out of the broccoli/cauliflower mixture and transfer the mixture to a large mixing bowl. You can squeeze out the liquid using a paper towel or a thin kitchen cloth (the cloth will work better). The less excess liquid, the better your garlic bread will turn out.
Step 3
In the large mixing bowl, stir the parmesan, egg, salt, pepper, garlic, and oregano into the mixture. Then, press the mixture into a 9×13 sheet pan lined with parchment paper, filling all the corners and edges.
Step 4
Bake the tray for 15 minutes. Then, sprinkle the cheddar cheese over the top of the garlic bread base. Bake for final 10 minutes – until the edges of the garlic bread are golden brown and the cheese is melted.
Step 5
Allow the garlic bread to cool for 5 minutes. Then, slide the parchment paper out from the tray, and slice the garlic bread into 12 rectangular slices. Enjoy!
