Ingredients You’ll Need (Your Quest Inventory):

 Marinade:

  • ⅓ cup lite soy sauce (the salty sea’s gift)
  • 1 tbsp. balsamic vinegar (a tart enchantment)
  • 1 tbsp. olive oil (the forge’s flame)
  • 4 tsp minced garlic (the bold warrior’s essence)
  • 1 tsp ground ginger (a fiery spark)
  • ¼ tsp black pepper (a whisper of shadow)

The Feast:

  • 1 flank steak (the hero’s prize)
  • 8 oz. fresh mushrooms, sliced (forest spoils)
  • 1 package onion mushroom gravy mix (the alchemist’s shortcut)
  • 1 package instant potatoes (the trusty base)
  • 1 bag frozen green beans (verdant allies)

Green Bean Sidekick:

  • ½ tsp ground black pepper (a bold flourish)
  • ¼ tsp salt (the seasoning charm)
  • 1 tbsp. Butter Buds (a golden touch)

 How to Forge Your Feast:

Step 1: Craft the Marinade Elixir:

In a large zip-lock bag, combine ⅓ cup lite soy sauce, 1 tbsp. balsamic vinegar, 1 tbsp. olive oil, 4 tsp minced garlic, 1 tsp ground ginger, and ¼ tsp black pepper. Pierce your flank steak with a fork on both sides, then plunge it into the marinade. Seal the bag and banish it to the fridge for at least 1 hour (overnight for max power).

Step 2: Broil the Beast:

Pull the steak from its marinade bath (discard the excess elixir) and place it on a broiler pan. Set your oven to broil, position the pan 3 inches from the heat source, and sear each side for 6 minutes.

Step 3: Harvest the Mushrooms:

 Slice 8oz. of fresh mushrooms and ready them for battle. Coat a medium skillet with cooking spray, heat it over medium-high, and sauté the mushrooms for 5 minutes.

Step 4: Conjure the Gravy:

In a small bowl, mix the onion mushroom gravy packet with water. Pour it into the skillet with the mushrooms. Bring it to a boil while stirring like a potion master, then reduce to low and simmer for 5 minutes until thickened. Stir in any steak juices from the broiler pan—waste not, want not!

Step 5: Assemble the Sides:

Cook the instant mashed potatoes according to the instructions. For the green beans, pan over medium heat with ¼ tsp salt, ½ tsp black pepper, and 1 tbsp. Butter Buds. Sautéing until nicely browned. 

Step 6: Claim Your Victory:

Slice the flank steak across the grain into ⅛-inch strips—precision is power! Heap a mound of mashed potatoes on each plate. Then layer it with sliced steak, and crown it with that glorious mushroom gravy. Serve with green beans on the side—your feast is forged!
