  4. OMG this is a forgiving recipe. I only had 1/2 a lb of sausage, so I cooked and added 12oz of crispy bacon, added 2 extra eggs and about an extra cup of cheese. This was so easy and quick to make, this literally disappeared in 20 min.

    Thank you!

  5. Hi 😊 I don’t have heavy cream right now, do you think cream cheese could work in place of it?? Thank you!!

    1. You could try that but you would probably need to add a little bit more liquid too. So maybe try 4 oz of cream cheese and 1/3 cup of nut milk, water or 2 extra eggs
