Steaks: Heat a grill pan over medium heat or preheat your gas or charcoal grill. Season the steaks on both sides with salt and herbes de Provence. Drizzle with olive oil and grill for at least 6 minutes on each side for medium rare or which every way you like your meat done. Let rest for 5 minutes before slicing. Thinly slice and top with the salsa.
Salsa: In a small bowl whish together the olive oil and balsamic vinegar, capers, parsley, salt and pepper until smooth. Add the bell peppers and toss to coat. Sometimes I can't find the yellow peppers, in that case I just use the red bell peppers only.
