Tre's Spinach Con Queso

In a heavy medium saucepan, heat oil over medium heat. Add onion and cook, stirring until limp and clear, 3 to 4 minutes. Add flour and cook, stirring, 1 minute.

Add spinach and green chilies. Cook and stir until well mixed, about 1 minute. Add cream and cook until mixture begins to boil, about 1 minute.

REDUCE HEAT to low and gradually add cream cheese, stirring until cheese is melted, 1 to 2 minutes. Gradually add the Monterey Jack cheese, stirring until melted. Do not allow mixture to boil or cheese will separate. Serve at once with tortilla chips for dipping. Serves 4 to 6.

Note: To keep mixture warm or to reheat, place over a pan of hot, but not boiling water.
