Bring 4 cups water and salt to a boil on the stove. Steam in the polenta, whisking continuously. Let barely simmer, barely!, for 30 minutes, stirring every 4 or 5 minutes, until thick and cooked through. Stir in garlic powder, butter and fresh parmesan. Pour into a flat, rounded baked sheet.
Let sit and cool, then press parchment paper down on top of it to cover and refrigerate. Let sit overnight, ideally.
For salsa, let shallots sit in red wine vinegar for 5 minutes. Then mix together with all ingredients. Let sit overnight, ideally.
When ready to serve, pat polenta with paper towels to dry moisture. Cut into inch by one squares. Heat 2 tablespoons olive oil over high heat on stove. Pan fry, letting sit on each side for five minutes, then flip. Do this in batches of 12, as to not crowd the polenta. Caution, polenta will splatter, so back away and let it do it’s things.
Mix greens with a little olive oil, salt, and pepper. Then top with fried polenta and 2 tablespoons salsa per plate. Serve.
