Serve these fluffy pancakes and their lively salsa as a first course or as a side dish. The provolone cheese brings out the flavor of the green onions.
To prepare salsa, combine first 9 ingredients in a bowl. Cover and chill.
To prepare pancakes, lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 5 ingredients (flour through black pepper) in a large bowl; make a well in center of mixture. Combine buttermilk and egg in a bowl; add to flour mixture. Stir just until moist. Let stand 10 minutes. Fold in green onions and provolone cheese.
Spoon about 1/4 cup batter onto a hot nonstick griddle or nonstick skillet coated with cooking spray. Turn pancakes when tops are covered with bubbles and edges look cooked (about 3 minutes). Serve salsa over warm pancakes.
