Season both baking sheets with salt and pepper, as desired. Roast in 450°F oven 30 to 35 minutes.
Meanwhile, prepare Southwest Tomato Cream. Heat medium nonstick skillet over medium heat until hot. Add onion; cook 5 minutes, stirring occasionally. Add beer, salsa, tomato paste and 1-1/2 tablespoons Six-Chile Spice Mix. Bring to a boil and simmer 15 minutes. Remove from heat. Gently whisk in sour cream. Keep warm.
