Heat oil and butter, about 2 tablespoons of each, in a large saut pan until very hot. Add veal to pan after dredging with flour and cook on both sides until brown. Remove to a plate.
Into the skillet the veal was cooked, add onions and salt, pepper and red pepper flakes to taste. Cook onions until soft. Then add garlic and cook for one minute. Now add white wine and cook until reduced to almost nothing. Add chicken stock and lemon and cook until reduced by half.
Then add capers and butter and swirl until this sauce becomes creamy doing this on very low heat. Remove from heat before the butter has finished melting. Add herbs and pour over veal to serve.
