I try to always have these burgers in the freezer.
Just put them on the grill and you feed a crowd very fast!
This makes about 8 burgers:
2 lb ground beef
I put in a food processor:
2 Tbs Dijon mustard
2 Tbs Worchestershire sauce
5 Tbs tomato paste
a dash of hot sauce or chili powder.
1 big onion
ground black pepper
Mix just until done (the onion kind of loose the water if you overdo it)
Work the sauce with the ground beef
Work a little bit more!
I weigh my burgers so they have the same size.
Put dollops on a cut plastic bag on a cookie sheet that fits the fridge.
Wash my hands, rinse in cold water and shape the burgers.
I make mine thicker around and thinner in the middle, makes them easier to grill!
Cover with plastic and freeze until next day.
Put them in plastic bags.
I normally make a BIG batch.
Served LCHF with veggies,cheese and a sauce of sour cream and blue cheese.
