Beat first 5 ingredients in large bowl with mixer until blended. Stir in cucumbers. Refrigerate until ready to serve.
Mix meat, onions and pepper just until blended; shape into 8 (1/4-inch-thick) patties. Spoon 1 Tbsp. feta cheese onto center of each of 4 patties. Top with remaining patties; pinch edges together to seal. Refrigerate until ready to use.
Heat grill to medium heat. Grill patties 4 to 5 min. on each side or until done (160°F). Spread half the cream cheese mixture onto bottom half of rolls; fill rolls with burgers, tomatoes and remaining cream cheese mixture.
Cream cheese mixture can be stored in refrigerator up to 2 days before using as directed. Patties can be shaped, stuffed and stored in refrigerator up to 8 hours before grilling.
Serve with a bagged green salad tossed with your favorite KRAFT Dressing, such as Italian or Ranch.
