Lentils, GOOD, low-fat smoked sausage, onion, a bit of celery, a can of tomatoes (roasted garlic flavored)...cook in the crock's pot until done.
Layer transparently-thin sliced potatoes, onions, and cubed lamb; put salt and pepper between each layer. Do NOT add carrots and/or celetery! Put in crock's pot and serve the old crock Irish stew.
