Combine 2 tablespoons each butter and flour, 1/2 teaspoon kosher salt and a few grinds of pepper in a saucepan; whisk over medium heat until foamy, about 2 minutes. Gradually whisk in 1 cup milk; cook, whisking, until thick, about 4 minutes. Add 3/4 cup grated Colby cheese, 1/4 cup chopped canned green chiles (drained), 1 diced plum tomato and 1 to 2 tablespoons chipotle hot sauce; stir until creamy.
