I'm a huge fan of the Kabob prices at upper cut meats.
For $1.50 / each, you have a selection of Lamb, Cajun Chicken, Beef, and Garlic Chicken. I highly recommend the Cajun Chicken and Lamb. The Lamb is high quality and lean. When cooked it doesn't have fatty chewy pieces that might turn some off.
For the effort to season the Cajun chicken and the large pieces of breast, this deal can't be beat.
Grab a tzatziki while you are there to go with the Lamb kabobs, you won't regret it.
