** Dutch oven ** Heat olive oil in dutch oven. Open can and slice corned beef, add into pot and saute for 5 minutes to heat. Remove and put into a bowl, set aside.
Pour broth into pot and scrape remnants of food off and into liquid. Slice large head of cabbage in half and then into 1.5x1.5" squares. Add those into your pot and stir.
Put lid on and allow to steam in pot for 5 minutes. Remove lid and drain liquid, then add corned beef and all seasonings. Fold together.
Heat for 3-5 more minutes to incorporate flavors. Taste, add more salt and pepper if you like. Serve.
** Air fryer ** Open can, set meat on a plate and put into fridge for 1 hour to harden more. Slice into 6 pieces. Preheat to 360 degrees for 5 minutes.
Spray basket with olive oil spray and lay sliced inside. Air fry for 4 minutes, open basket and lightly spray tops with olive oil. Air fry for another 2 minutes or until outsides as browned to your liking. Sprinkle with salt and pepper and enjoy.
** Sandwiches ** Mash canned meat in a bowl and add enough mayonnaise to make it wet, as you would when making tuna fish. Fold in 1-2 tbsp relish and diced celery and spread this on toast or two slices of bread to enjoy.
