Mix all the ingredients for the meatballs together in a bowl and allow it to sit for at least 15 minutes. After the time, roll the meatballs by hand.
In a pan on medium high heat, add a little oil then sear the meatballs on 1 or 2 sides. Do not try to cook them all the way through, just sear them then remove them from the pan.
Lower the heat of the pan to medium and you'll need about 1/4 cup of leftover dripping from the meatballs, discard the rest.
Add in the flour and whisk the flour with the leftover dripping while scraping the bottom for about 1-2 minutes. Then, whisk in the beef broth.
Crumble the bouillon cubes into the gravy and whisk in. Now, add the meatballs back in and lower the heat to low and allow the meatballs to cook all the way through in the gravy. Depending on the size, this could take 10-15 minutes.
Once the meatballs are cooked through, allow to cool a bit then serve and enjoy!
