Step 1

Add oil to a medium-sized saucepan and bring to temperature over medium-high heat. Add the diced onion and jalapeno and saute until softened, stirring often, about 6 minutes.

Step 2

Reduce the heat to medium. Add the cubed cheese and evaporated milk, and stir occasionally until melted and smooth.

Step 3

Reduce the heat to low, add the Monterey Jack, garlic powder, and salt and stir until smooth. Add the chopped tomatoes and cilantro and stir once more.

Step 4

Transfer to a serving vessel, serve with tortilla chips, and enjoy!
