Ingredients:

* 1 lb. lean ground beef
* 2 Tbsp. chopped parsley
* 1/2 cup creamy Caesar salad dressing
* 3 Tbsp. grated Parmesan cheese
* 1/2 tsp. seasoned salt
* 1/8 tsp. pepper
* 1 sweet onion, cut into 1/4" slices
* 4 leaves Romaine lettuce
* 4 kaiser buns

Preparation:
Prepare and heat grill. Combine beef, parsley, 3 Tbsp. salad dressing, Parmesan cheese, seasoned salt, and pepper and mix gently. Shape into four patties, each about 1/2" thick. Grill patties on covered grill 4-6" from heat for 12-15 minutes, until hamburgers are no longer pink in center. Turn once, brushing with remaining salad dressing. Grill onions for last 8 minutes of grilling time, brushing with some of the dressing. Discard any remaining dressing. Serve on sandwich buns, grilled if you'd like, with lettuce.
