Clean and dry the beef and place it in the freezer for about 20-30 minutes – chilled meat is easier to cut. In the meantime, prepare the other ingredients. Wash, peel, and grate the ginger. Peel the garlic clove and press it through a garlic press.

In a dish, combine ginger, garlic, sweetener, fish sauce, sesame oil, and soy sauce. Mix thoroughly.

Cut the meat into thin, long strips. Then coat them in the prepared marinade. Refrigerate for at least 2-3 hours, ideally overnight (you can skip marinating, but the flavor will be less intense).

Before taking the marinated meat out of the fridge, prepare the peanut sauce. Peel and finely chop the onion and garlic. Finely chop the peanuts. Heat butter in a pan. Then add onion and garlic. Sauté for a while on medium heat, stirring constantly. Add sweetener, peanut butter, soy sauce, and a bit of water (1-2 tablespoons or more, depending on the need). Sauté again for a while, stirring constantly. At the end, add the peanuts. Mix thoroughly. Transfer to a small bowl. Eat warm or cold.

Thread each strip of meat onto a skewer (you can thread several strips onto one skewer).OVEN: Transfer the skewers onto a baking tray lined with baking paper. Place in a preheated oven at 180°C and bake until properly cooked, about 10-12 minutes. GRILL: Place the skewers on a hot grill/grilling pan and grill until properly cooked, about 2-3 minutes on each side.

Serve on a plate with peanut sauce.
