Lightly oil the escarole, artichokes, tomatoes, and shallots and place on the grill. Grill until tender, removing as they finish and placing on a large platter.
Press down on the trout to completely open and flatten. Season the flour with Essence, salt, and pepper and place in a shallow dish. Dredge the trout in the seasoned flour. Add butter and oil to a hot saute pan. Pan-fry the trout until golden brown on both sides and cooked through, about 4 minutes per side.
Place the fish on top of the grilled vegetables and top with balsamic vinegar, lemon zest, and parsley.
Combine all ingredients thoroughly and store in an airtight jar or container.
Yield: about 2/3 cup
