Ingredients

• 500 grams Beef sirloin or ribeye
• 3 medium Zucchini
• 2 tablespoons Fish sauce
• 2 tablespoons Lime juice
• 2 tablespoons Soy sauce (or tamari for gluten-free)
• 1 tablespoon Sesame oil
• 1 tablespoon Erythritol sweetener
• 3 Garlic cloves
• 2 Shallots
• 6 Lettuce leaves
• 1 cup Fresh mint leaves
• 1 cup Fresh cilantro
• 1 cup Fresh basil
• 1 Chili pepper
• 2 tablespoons Crushed peanuts
• 1 small Cucumber

Directions

Step 1

Thinly slice the beef across the grain into bite-sized strips.

Step 2

In a bowl, combine 1 tablespoon fish sauce, 1 tablespoon lime juice, 1 tablespoon soy sauce, and 1 tablespoon sesame oil. Grate 2 garlic cloves and 1 shallot, then add to the mixture. Mix well and add the beef slices to marinate for at least 15 minutes.

Step 3

While the beef is marinating, use a spiralizer to create zucchini noodles. Set aside.

Step 4

To make the dressing, combine the remaining fish sauce, lime juice, soy sauce, erythritol, and grate 1 garlic clove and the other shallot in a small bowl. Stir until erythritol is dissolved.

Step 5

Heat a skillet over medium-high heat. Once hot, add the marinated beef in batches if necessary to avoid overcrowding. Sear for about 2-3 minutes per side or until cooked to your liking.

Step 6

In a large bowl, add the zucchini noodles, lettuce leaves torn into bite-sized pieces, thinly sliced cucumber, and half of the fresh herbs (mint, cilantro, and basil). Toss with half of the dressing.

Step 7

Divide the salad among serving bowls, top each with the cooked beef slices, and sprinkle with crushed peanuts and chili slices.

Step 8

Garnish with the remaining herbs and serve with extra dressing on the side.
