Preheat your oven to 425º and adjust your oven rack to the middle level.

In a medium sized bowl, add your frozen cauliflower and drizzle with olive oil.

Sprinkle on the salt and add 1 teaspoon of lemon pepper seasoning if using a 10.8 oz bag of cauliflower or 1 1/2 teaspoons for a 12 oz bag.

Using a rubber spatula, toss all the ingredients together until the cauliflower is well coated.

Pour the frozen seasoned cauliflower onto a sheet pan in a single layer. Do not overcrowd the pan, you need air to get in between all the florets.

Place the sheet pan in the preheated oven and roast for 15-18 minutes until the cauliflower is tender and browned along the edges.

Remove the roasted cauliflower from the oven and serve. Add more salt if desired.
