This is a simple dish to throw together with leftover meat. I use frozen vegetarian steak strips, though sliced seitan, seared flank steak or any other protein would probably work.
Heat the olive oil in a large skillet. Sear steak strips, bell peppers and onion together with salt and red pepper flakes for a few minutes, then turn heat down and add crushed tomatoes and capers. Simmer, covered, for ten minutes or until steak is cooked through and tender. Chiffonade the basil and add, simmer for another couple of minutes.
Serves four. Good as a main dish with spinach and garlic and risotto.
