Grilled Flank Steak

Flank steak is one of my favorite protein options for a quick and satisfying meal. Protein is essential for maintaining muscle mass, supporting cognitive function, balancing blood sugar, and helping you feel full and energized throughout the day.

When choosing beef, I recommend selecting grass-fed and organic whenever possible. Grass-fed beef contains beneficial nutrients, including omega-3 fatty acids and antioxidants, compared to conventionally raised beef. It is also free from many of the additives commonly used in conventional farming practices.

This grilled flank steak recipe cooks quickly and develops a delicious crust while remaining tender and juicy. Slicing the steak against the grain helps create the perfect texture. Pair it with grilled vegetables such as zucchini, asparagus, cauliflower, or Brussels sprouts for a complete AIP-friendly meal.

Making the Chimichurri

Traditional chimichurri is known for its fresh herbs and vibrant flavor. This version includes parsley, mint, garlic, avocado oil, apple cider vinegar, lime juice, and lime zest.

Parsley is rich in antioxidants and vitamin C. Mint adds a refreshing flavor while providing beneficial plant compounds. Garlic contains sulfur-containing compounds that support overall wellness. Avocado oil provides healthy monounsaturated fats that help support cellular health. Apple cider vinegar and fresh lime juice bring brightness and acidity that perfectly complement the rich flavor of the steak. 

These simple ingredients create a fresh and flavorful sauce that elevates this chimichurri steak recipe. The final ingredient is what makes this recipe unique. I add a scoop of ImmuneIG to the chimichurri for additional gut and immune support.

Immunoglobulin G Benefits

ImmuneIG contains ImmunoLin®, a serum-derived bovine immunoglobulin concentrate that provides immunoglobulin G.

Many people ask me about immunoglobulin G benefits and how immunoglobulins work in the body. Immunoglobulins are specialized proteins that support immune and gut health. They work within the digestive tract to help maintain a healthy gut barrier and support immune resilience.

The gut is home to a large portion of your immune system. Supporting gut health can play an important role in overall wellness. That is why I often focus on nutrition and targeted supplements that help support a healthy digestive environment.

One serving of ImmuneIG provides concentrated immunoglobulins that can easily be mixed into smoothies, beverages, and recipes such as this chimichurri sauce. It has a neutral taste, making it simple to incorporate into your daily routine. Many people exploring colostrum should consider ImmunoLin® because it is a dairy-free alternative.
