gravy granules instead of oxo cubes?

[natalie_mcrmy]

I'm wanting to make this https://www.philadelphia.co.uk/Recipes/Steak-with-Philly-Sauce?r=18381 but it says to use beef oxo but I don't have any. Do you think it would be okay to use gravy granules instead and if so how much do you think I should use?

I'm not sure on amounts to use, but remember to syn it as oxo cubes are free but gravy is not x
