Preheat oven to 400 F. Line a sheet try with parchment paper, if you prefer.

Make a spice blend by combining the Aleppo pepper, Sumac, smoky paprika, garlic powder, and salt, stirring to combine thoroughly.

Break up the cauliflower into florets. Toss with olive oil to cover thoroughly. Then cover evenly with the spice to coat.

Place on the sheet tray and roast in the oven for 20 minutes. Then flip the cauliflower and continue to cook for 10-15, or longer if desire a crispier cauliflower. Serve
