Steak Fingers with Salsa Verde

Salsa
6 poblano or anaheim chiles
1/4 C crushed tomatoes
1 tsp vegetable oil
1/4 tsp garlic powder
1/4 tsp onion powder
1/4 tsp dried red pepper flakes
1 tsp flour

Broil chiles on baking sheet, turning them as their skin blisters and chars on all sides, about 5 minutes per side. Transfer to a bowl, cover with plastic wrap and set aside to cool. Pull off stems, peel, then tear chiles open and scrape out seeds. Discard stems and seeds. Chop chiles and set aside. Put tomatoes, oil, garlic and onion powders, pepper flakes, reserved chiles, and 3/4 cup water into a medium pot. Bring to a boil over high heat, then reduce heat to medium-low. Whisk together flour and 1 tablespoon water in bowl, then whisk into salsa. Simmer, stirring often, until thickened, 8-10 minutes. Season to taste with salt. Keep warm over low heat.
