Heat a pot on medium heat and add 2 tbs of butter and 2 tbs extra virgin olive oil.
Next add onions and season with salt and pepper. Let the onions cook (stir occasionally) for a minute.
Now add garlic and cook for 30 seconds. (only cook garlic a short period of time because garlic burns fast)
Add the cabbage and season with salt, pepper, and red pepper flakes. Cook for 1 minute, stir occasionally (till the cabbage wilts a little).
Now add the corn beef and mix with rest of ingredients. (heat for 30 seconds)
Turn the heat off and add in the Parmesan cheese and dill.
Cheers to pasta fun!
