Shepherd's pie, but better! Better tasting and better for you. This recipe has meat but I'm sure if you're veg you can think of a delicious substitute and this will just serve as inspiration for your next creation.

4 Yams (you can use sweet potatoes too, but yams are cheaper, dontcha know?)
1 Small yellow onion
1 Clove of garlic
2 Carrots
2 Stalks of celery
1 Cup of frozen corn
1 Cup of frozen peas
1 Cup of beef broth (or your substitute)
1 Package of lean ground beef (maybe ground turkey or chicken would be nice)
2 Tsp of italian seasoning blend
Salt and pepper

1. Boil peeled and cubed yams. Mash with italian seasoning blend and a bit of butter and milk.
2.While yams are bowling chop and soften the veg.
3. Cook the meat

Mix the meat and veg together with the beef broth and put into a 9x11 dish. Top with mashed yams and cover to cook at 350 for 30 minutes. Uncover and broil for 10-15 minutes to get a crispier top.
