I LOVE grilling season!!! Spring and summer time means that I marinate, and the husband grills. It’s the perfect arrangement! Flank steak is one meat that is a nice occasional treat and variation from our traditional chicken and vegetable regimen. It’s also one the kids always look forward to. I have a few flank steak marinades that I love, but this one is particularly my favorite because it reminds me of our family trip to Greece.

After our recent trip to Greece, I’ve been thinking about all the delicious meals we ate. Beef Souvlaki was one of our favorites and I wanted to bring the taste of our vacation to our home! Souvlaki is kabob style, but because I love the cut of a flank steak, I chose to nix the kabobs. The marinade is a tangy blend of lemon, Dijon mustard, red wine vinegar, and spices. For best results, marinade a full 24 hours. The Tzatziki is easily thrown together while your meat is on the grill. I have included a dairy-free option so that my husband and I could enjoy this on Whole30. It pairs so well with my Cauliflower Rice Tabbouleh!

For a crowd pleasing dinner, serve with a traditional Greek Salad or with my Cauliflower Rice Tabbouleh. Another option with this dinner is to wrap everything in a pita for a gyro type sandwich.

Ingredients

• For the beef:
• 2 lbs Flank Steak
• 1 cup olive oil
• 1/4 cup fresh lemon juice
• 1/4 cup coconut aminos or soy sauce
• 1 tbsp lemon zest
• 1/4 cup red wine vinegar
• 1 tbsp Dijon mustard
• 2 tbsp fresh chopped mint
• 1 tsp dried oregano
• For the Tzatziki:
• 3/4 cup plain Greek yogurt or 1/2 cup coconut cream*
• 1/4 cup fresh lemon juice
• 1/2 cup finely chopped cucumber
• 2 tbsp chopped fresh dill
• 2 tbsp chopped fresh mint
• 1 clove garlic crushed
• 1 tsp salt

Instructions

1. Prepare your meat: place your flank steak in a large container or dish (I use a 9x9 baking dish). Mix the remaining ingredients and pour over steak until completely covered. Marinade for at least 8 hours, up to 24 hours.

2. Heat up your grill. Grill approximately 5-8 minutes per side (depending on how you like your meat cooked). Continue to baste the meat with additional marinade while cooking to enhance the flavor. 

3. While meat is grilling, make your tzatziki sauce. Whisk together all ingredients, salt to taste.
4. To cut meat, slice on the diagonal against the grain.
5. Serve hot with Tzatziki and Greek salad or with my Cauliflower Rice Tabbouleh
