Heat 1 tablespoon oil in a pan over medium-high heat. Crush 1 clove of garlic and fry for 1-2 minutes until golden brown. Roughly chop the broccoli, cauliflower, carrots, bell peppers and onions, add to the pan and fry for 2 minutes. Add 1 tablespoon sugar and cook over medium heat for 2-3 minutes to caramelize.
Cut 400 g of meat into thin slices across the grain, add to the pan and fry for 2-3 minutes. Add 2 tablespoons peanut butter and immediately deglaze the pan with 1 can (approximately 300 ml) of coconut milk. Season to taste with 2 tablespoons light soy sauce or a pinch of salt and pepper. If the sauce is too thick, add water gradually until you reach the desired consistency.
