This is my favorite stew--I just toss it all in the crock pot and it's really good.
1 lb (about 2 large) peeled sweet potatoes (you can use regular, too)
1 lb carrots
1 medium yellow onion
2 lb top sirloin
3 tbsp reduced-sodium soy sauce
3 tbsp ground flaxseed meal
1 1/2 cups low-sodium beef broth
1 1/2 cups water
And that's it. I cook it all day in the crock pot, and add a bit of flour near the end if it seems like it needs thickened up.
