Update: Feel free to cook the meat as directed below, but our new favorite way to prepare the meat is found here: crispy beef & pork
2 c. giardiniera pickled vegetables, plus 1 Tbs. brine
1/4 c. mayonnaise
1 1/2 lbs. shaved steak (or slice it as thin as you can)
1 tsp. garlic powder
salt & pepper
2 Tbs. vegetable oil
1/4 c. finely chopped onion
1/2 tsp. dried oregano
1 tsp. minced garlic
1 tsp. flour
2 c. beef broth
4-8 ciabatta rolls split lengthwise
1. Pulse giardiniera and mayonnaise until finely ground, set aside.
2. Season the beef with garlic powder, salt, and pepper.
3. Heat 1 Tbs. oil in a skillet over medium heat. Add half of the beef, breaking up any clumps, cook for 2-3 minutes. Remove from skillet and repeat with remaining oil and beef. Remove to a plate.
4. Add a little oil and onion to now-empty skillet, cook for 1-2 minutes. Stir in oregano, garlic, and flour. Then add the broth and brine, scraping up any browned bits. Simmer until the mixture reduces to 1 cup, about 8 minutes.
5. Turn off the heat, add the beef back to the skillet and stir to combine.
6. Spread giardiniera mixture on rolls, then top with beef.
