Chili con Queso

Directions

1. In a saucepan, heat butter over medium-high heat; saute onion and garlic until tender. Add chiles; cook and stir 5 minutes. In a small bowl, mix cornstarch and milk until smooth; stir into onion mixture. Bring to a boil; cook and stir until thickened, 1-2 minutes.
2. Reduce heat to low; gradually stir in cheeses, adding in small amounts and allowing cheese to melt between additions. Serve warm with chips. If desired, top with tomato and jalapeno.
