  • (2 TBS) Balsamic Vinegar
  • (2 TBS) Olive Oil
  • (2 TBS, chopped) Fresh Parsley
  • (2 tsp) Salt
  • (1 tsp) Black Pepper
  • (2 tsp) Garlic Powder
  • (4 TBS) Salted Butter
  • (2 cups) Baby Bella Mushrooms
  • (1 cup, diced) Onion
  • (2 TBS) Sugar
  • (1/2 cup) White Wine Vinegar
  • (1 TBS) Olive Oil
  • (2 tsp) Garlic Powder
  • (1/3 cup) Mayonnaise
  • (1/3 cup) Sour Cream
  • (2 TBS, chopped) Fresh Parsley
  • (2 TBS, chopped) Fresh Dill
  • (2 TBS, chopped) Fresh Chives
  • (2) Ciabatta Bread
  • (6 slices) Provolone Cheese

Directions

To make the steak, begin by patting it dry and place it in a bowl. Add in 1/2 cup brown sugar, 2TBS balsamic vinegar, 2TBS olive oil, 2 TBS fresh chopped parsley, salt, and pepper. Allow to marinate for an hour or refrigerate overnight. Once the steaks have had time to marinate, cook them over medium heat to your desired cooking temperature. I prefer a medium-rare steak - this is about 5 minutes on each side over the stove. Once the steak is cooked, allow it to rest, then slice in thin strips against the grain. 

To make the caramelized onions and mushrooms, bring a skillet to medium-high heat and melt the butter. Add in the sliced mushrooms and diced onions and cook them down for about 5 minutes. Sprinkle the onions and mushrooms with 2TBS of sugar, tossing to coat evenly. Deglaze the pan with white wine vinegar (can substitute with balsamin vinegar), and bring everything to a boil, stirring occasionally. Lower the heat and allow to simmer for about 20 minutes or until caramelized. 

For the garlic and dill sauce, in a small bow, combine the mayonaise, sour cream, olive oil, parsley, dill, chives, garlic powder, salt and pepper.

To assemble the sandwhich, put your oven at a high broil and line a baking sheet with parchament paper. Arrange the sliced bread on the baking sheet. Layer the steak on each sandwich, then top with provolone cheese. Place the baking sheet in the oven and cook until the cheese is melted. Remove the pam from the oven and top sandwiches with caramelzied onions and mushrooms, and kale (can substitute with arugula). Spread the other half of the sandwich with the garlic and dill sauce. 

Herbed Golden Potatoes with Fennel

Golden potatoes grown with regenerative farming practices are cooked alongside fragrant fennel to create a bright, comforting side dish. The potatoes become tender on the inside as they cook in olive oil and rich grass-fed butter. Fresh lemon juice adds a lively citrus note that balances the sweetness of the fennel and the buttery potatoes. Finished with salt, cracked pepper, and a lot of fresh parsley, this simple dish highlights wholesome ingredients and the vibrant flavor of regeneratively grown produce.

Mustard And Dill Roasted Potatoes

Roasted Regenerative Purple Potatoes feature small, regeneratively grown purple potatoes roasted until perfectly crispy on the outside and tender inside. Their rich color and naturally earthy flavor shine when simply seasoned and roasted to golden perfection. Served alongside a creamy Dijon mustard dill sauce, the dish balances crispy texture with a smooth, tangy, herb-forward finish. Made with potatoes grown using regenerative farming practices that support healthy soil and biodiversity, this simple yet vibrant side brings both bold flavor and thoughtful sourcing to the table.

Oven Roasted Crispy Parmesan Potatoes

These oven-roasted crispy Parmesan Potatoes are made by slicing and lightly scoring regeneratively grown potatoes so they roast up extra crispy while staying soft and fluffy inside. The potatoes are coated with rich grass-fed butter, garlic, and grated Parmesan cheese, then roasted until golden brown with crispy edges and a savory, cheesy crust. Using regeneratively grown potatoes and grass-fed butter highlights ingredients raised with soil health, biodiversity, and sustainable farming in mind—creating a simple, comforting dish that’s both flavorful and thoughtfully sourced!
