Whisk the ingredients for the marinade in a small bowl
Place the skirt steak and the marinade in an air tight container or zip lock bag and marinade for at least and 30 minutes or up to 24 hours. I like to do this the night before and let it sit in the fridge and marinate the whole next day.
Pre heat the oven to 475 degrees Fahrenheit
Line a baking sheet with foil and place bell peppers, onion, and potatoes on the sheet pan
Coat veggies with avocado oil and season with salt, pepper, garlic powder, and onion powder
Bake veggies for 15 minutes then take the pan out of the oven and turn the oven to a hi broil
Remove the skirt steak from the marinade and nestle it between the veggies on the sheet pan
Return sheet pan to the oven and broil for 4 minutes a side (this will give you a nice medium steak. Cook a few minutes longer per side for a more well done steak)
Notes
Steak- you can use flank steak or even bison skirt or flank steak in this recipe. I love using bison skirt or flank steak if I can find it at the grocery storeBell peppers- any color bell pepper will work in this recipePotatoes- If you don't have Yukon gold potatoes, you can use red or purple potatoes
