Preheat oven to 425. Line 14 mini muffin cups with silicone liners, or foil muffin liners with paper liners removed. Spray liners with non-stick cooking spray. Set aside.
Wash cauliflower, and cut in half, (save the rest for later). Break cauliflower into segments, and place in food processor. Pulse until it reaches a rice-like texture.
Place cauliflower in microwave safe bowl and microwave for 8 minutes. (Do NOT add water or cover).
Remove cauliflower from microwave and add the rest of the ingredients. Stir to combine. Place back in microwave for 2 minutes. Mix again.
Scoop cauliflower mixture into muffin liners, dividing evenly between the 14 mini liners. Fill to the top, and press filling down so it’s compact in liner.
Place muffin tin in the oven and bake muffins for 30-35 minutes, or when top starts to become golden brown. Remove from the oven, let cool completely before popping the muffins out of the liners. Serve warm with pizza sauce for dipping!
