Thai Beef Salad

Step 1
Mix lime juice, cilantro, mint leaves, sugar, fish sauce, green onions, lemongrass, and chili sauce together in a large bowl until sugar is dissolved. Adjust the flavor, if desired, by adding more sugar and/or fish sauce; set aside.

Step 2
Preheat an outdoor grill for high heat and lightly oil the grate.

Step 3
Cook steak on the preheated grill until it begins to firm and is hot and slightly pink in the center, about 4 to 6 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C).

Step 4
Transfer steak to a chopping board and slice into thin strips; add steak and its juices into the bowl with herb mixture. Cover and refrigerate for at least 3 hours.

Step 5
Place lettuce in a salad bowl; arrange cucumber on top. Add steak and pour all of the herb mixture on top. Scatter cherry tomatoes over salad and garnish with fresh cilantro leaves.
