I made this recipe up, loosely based on Salisbury Steak and German meatballs. It turned out to be delicious!
1 lb. ground beef (I used 85/15)
1/4 cup caper juice with a few capers
1/4 cup oatmeal (quick oats or regular)
1/2 onion, diced
1/2 green pepper, diced
1 egg, beaten
2 tbsp butter
1 tsp garlic powder
1 tsp thyme
Salt and pepper to taste
Start with 1/4 cup of caper juice with a few capers (~12) in a big bowl. Add in the oatmeal, and toss to absorb the juice. Add 1 lb. ground beef, onion, and pepper, and mix with hands.
Mash the butter into the egg, along with some salt and pepper. Add the thyme, garlic powder, and salt and pepper on top, then mix again with your hands.
Divide the meat mixture into 4 equal parts, and form them into oval-shaped patties. Preheat a pan on medium-high heat. Add the patties. Allow them to cook 3-4 minutes on each side.
If you'd like to make a sauce, use wine or wine-based vinegar to deglaze the pan. I used white wine vinegar, cut with a little bit of water and a dash of worcestershire sauce, but I think red wine vinegar or cooking sherry would be even better. Scrape the pan to release all the browned bits. Add some sliced mushrooms, green bell peppers, and capers. Simmer until the sauce reduces by half. I added in some corn starch at the end to thicken it up. Finish the patties off by cooking them in the sauce, or pour it all over the top.
I served these with sliced, roasted sweet potatoes and sliced, baked zucchini. Delicious!
