6 fresh hot jalapeno chilis, cored, seeded and halved
( use less according to the hotness you desire)
1 small onion, peeled and quartered
½ medium red pepper, cored, seeded and cut into 1 inch pieces
12 oz Monterey Jack cheese, cut into 1 inch pieces
1 t cornstarch
¾ c milk

In a food processor with the metal blade, pulse the chilis, onion and pepper 4 times.  Scrape down the sides and pulse 4 more times until finely chopped.  Remove.
Pulse the cheese and cornstarch twice and then process for 10 seconds or until finely chopped.  Scrape down the  the sides.  Bring the milk to just a boil over medium-high heat.  With the motor running, pour the hot milk through the feed tube and process until smooth about 10 seconds.  The mixture will be very thick.
Return the mixture to the pan and stir in the reserve chopped vegetables.  Cook over medium heat, stirring often until it thins, about 5 minutes.  Continue cooking until the mixture simmers and thickens to coat a spoon heavily.
