Preheat a 12” heavy skillet or wok over medium high heat. Add olive oil and heat for one minute.
Add ground beef to the skillet and cook for 5-7 minutes or until the meat starts to brown.
Add onions, garlic and carrot to the skillet with the ground beef. Stir together and cook for an additional 2-3 minutes until the vegetables start to soften.
Once the onion/garlic/carrots have softened, add broccoli and chopped water chestnuts. Cook for an additional 2-3 minutes or until broccoli starts to soften.
While the meat cooks, mix together your sauce of coconut aminos, rice wine vinegar, sesame oil, pepper, ginger and red pepper flakes. Stir to coat the meat/veggies in the sauce and cook for an additional minute.
Place about ¼ cup of the cooked ground beef mixture on the leaves of the lettuce, top with a sprinkle of sesame seeds and some green onions. Enjoy!
