Spicy cheddar-jalapeno dip

We're heading over to a friend's place for an afternoon of football watching, and I'm taking my own advice: Bring something clean that you will enjoy eating. This dip does the trick with an entire bag of baby spinach and a head of cauliflower; there will be very little guilt enjoying this. I used Greek yogurt instead of mayonnaise and will heat it up once we arrive at their place. But I did sneak a taste, and now I am eager to get on the road;)
