In a small bowl, whisk together the first 6 ingredients (basil through salt and pepper).
Sprinkle this mixture evenly over the steak strips, rubbing in to help the flavors penetrate the meat.
Preheat oven to 350 degrees.
In a large ovenproof skillet, heat 2 tablespoons of ghee over medium-high heat.
Cook beef strips approximately 1-2 minutes each side, until brown.
Meanwhile, heat remaining ghee in a separate large skillet over medium heat.
Add onion and cook until softened, about 2 minutes, and then add garlic and continue cooking for 1 minute.
Add zucchini and bell pepper, and cook 4 minutes, until soft.
Add artichoke hearts and olives, and continue cooking 3-4 minutes, until all vegetables are softened.
Serve vegetables alongside steak.
