Preheat oven to 400 degree Fahrenheit.Transfer the frozen cauliflower florets to a large bowl.
Drizzle olive oil in the cauliflower florets.
Sprinkle salt and all the spice powders. Also add the lemon juice.
Then toss the florets in spices, oil and lemon juice very well using a large spoon or spatula so all the ingredients are combined evenly and the florets are coated well with the spice mix.
Line a baking sheet with aluminium foil.Layer the cauliflower florets in a single layer in the baking sheet.
Bake in the preheated oven for about 30 minutes until the florets are well roasted and begins to brown on the edges.
Once baked, immediately transfer the roasted cauliflower from the oven and transfer the roasted florets from the baking sheet to a serving dish.
Serve the delicious oven roasted cauliflower florets as a side along with rice or serve it as a healthy snack with any dip of your choice. I just love to have it as it is as a healthy snack they are so delicious on its own!
