I pulled out the grinder, and in went:
Lamb stew meat
Onion
Bread
That all went into a bowl and I added:
1 egg
Penzey's Greek Seasoning
Penzey's dried red and green peppers
Cracked rosemary
Salt and pepper
I mixed it up, formed meatballs, browned them in a pan and finished them in the oven.
The sauce was:
Greek-style yogurt (home made)
Onion, finely diced
Cucumber, finely diced
Salt
Everything was "to taste" and when it was all done, it tasted pretty good.
