1 lb ground turkey
1 cup chopped spinach (I always use fresh, I've never used frozen...I'm sure it'd work, but recommend fresh) I think this is the key to keep it moist.
1/4 envelope Lipton Onion (or Beef) soup mix
3 Tbs. ketchup
A few splashes worcheshire sauce (that just took me 10 minutes to find the spelling)
1/4 cup grated parmesan cheese (again, I always use fresh, not the green can. You can substitute any cheese you'd like)
12 saltine crackers (smashed into fine crumble) I have also used goldfish crackers...VERY good!
1 egg
Mix altogether until combined. I try to handle as little as possible. I don't use a loaf pan (maybe I'm just opposed to the word loaf, I don't know!) but I form mine into mini football shapes. I make 5 out of the mix. I get a pan on top of the stove piping hot with a little olive oil, then add the mini loaves to get a good sear on them...I finish them off in the oven (375 for 20 minutes or until done)
You can make a lot of variations to this: different crackers, add real onion, add zucchini, different cheeses, BBQ sauce instead of ketchup...it's a pretty easy "no-fail" recipe.
Enjoy!
