Make sure to disinfect and clean your knife and cutting surface after working with raw meat. Season the beef cubes with salt and pepper.
  • In a GoodCook Classic Sauté Pan, heat olive oil over medium-high heat. Toss the butter into the pan, then immediately add the steak cubes. Cook until golden brown on one side, then turn in pan, cooking until golden brown on all the other sides.
  • Add garlic and balsamic to the pan. Cook, stirring often until the vinegar begins to thicken.
  • Transfer the balsamic beef into the 1-cup section of a GoodCook meal prep container.

For the Spinach Cauliflower

  • To cook the frozen mashed cauliflower and spinach for this recipe: Add the frozen mashed cauliflower to a GoodCook Classic Sauté Pan and heat to medium-high. Toss in the puréed garlic and the baby spinach.
