Steak Nachos

Spray a frying pan with cooking spray. Heat over medium heat. Cook and stir steak until barely any pink remains, 5 to 7 minutes. Drain fat from pan; add taco seasoning to the steak. Let simmer until desired consistency is reached, 3 to 5 minutes.

Warm milk in a medium saucepan over medium heat until small bubbles appear along the sides. Remove from heat.

Melt butter in another medium saucepan over medium-high heat. Add flour once bubbles disappear. Cook, stirring constantly with a whisk, until mixture becomes paste-like and light golden brown, about 5 minutes. Gradually whisk in the warm milk and bring to a simmer over medium heat. Cook and stir until the mixture is thick and smooth, 10 to 15 minutes. Reduce heat to low and stir in shredded cheese.

Add black beans, salsa, and the steak pieces. Stir and serve with tortilla chips.
