my first thought was souvlaki. souvlaki is another term for kebab made with all meat.
marinate the cubes in garlic, oregano, lemon, s&p, sugar, and olive oil. if you like lamb and happened to have saved it, add the fat from frenched lamb chops or a lamb roast to inject another level of flavour. it will tastes somewhere between lamb and beef, and is much cheaper than all lamb.
skewer cubes and charcoal grill until medium rare to medium.
serve with a grilled pita and salad of greens, tomatoes, cukes, onions, green peppers, feta cheese, and kalamata olives dressed in evoo and red wine vinegar.
A true lover of nature does not despair now that his mistress has turned a colder cheek.
