It's me Alissa here. I love cheese burgers! I never really craved them too much until my oldest was born close to 5 years ago.
I actually mixed in oatmeal into the hamburger. If you want less texture, you can use a mini food chopper to grind up the oatmeal up before adding it to the meat.
I also added chopped green onion, tomatoes, garlic, feta cheese and a dash of worceshire sauce.
The burger had wonderful flavor! There really wasn't that much feta cheese in the mix. I didn't add additional cheese on it.
We try and get meat that is low in fat.
