If using customized protein, do not roast. Cook in a medium non-stick pan over medium heat with 1 tsp. olive oil.
If using steak strips, separate into a single layer, pat dry, and coarsely chop. Stir occasionally until no pink remains and steak reaches minimum internal temperature, 4-6 minutes. Rest, 3 minutes.
If using Impossible burger, break up burger into smaller pieces until heated through, 4-6 minutes.
