In a saucepan, add the cream and start stirring slowly, very slowly.

If it's very thick, add some milk to loosen it up a little. Also add some finely chopped garlic cloves (better if they are roasted).

Add grated cheese to the cream. Quantity of cheese can be as per your wish.

Keep heating the mixture at low and add some butter to it. The butter enhances the taste of the cheese.

Add oregano, pepper and chili powder to the mixture.

The mixture will smell cheesy and full of oregano. When the mixture is loose yet thick, put off the flame.

Add the sauce to the mixture of pasta and sautéed veggies, and your done!
