For the kabobs, combine about 1/2 cup EVOO with the garlic, oregano, lemon juice, crushed red pepper flakes and a liberal dose of salt and pepper. Add meat to marinade and coat; then chill a minimum of 2 hours.
Skewer the meat on metal kabobs. Skewer peppers, onions and bay leaves on separate rod or two and dress with light coating of EVOO, some salt and pepper. Preheat a double-burner grill pan over medium-high to high heat or a broiler to high heat and arrange the oven rack about 6 inches from broiler.
In a medium saucepot with a tight-fitting lid, melt butter over medium heat. Add orzo and stir until golden brown and nutty in fragrance. Add rice, stir to combine then add stock and bring to boil, reduce heat to simmer and cover pot.
Grill or broil kabobs or brochettes 12-16 minutes for medium-rare to medium-well doneness, turning occasionally.
In a food processor, combine herbs for the pilaf, the garlic, lemon juice, about 1/4 cup EVOO, salt and pepper. Pulse until finely chopped.
After the rice has been cooking for 10 minutes, stir chard and scallions into the pot. Cover and cook 7-8 minutes more then stir in herb mixture.
Serve rice on plates or platters topped with feta crumbles. Serve meat, peppers and onions on top.
