Don't get thrown off by the sugar and the vinegar, the flavors work really well with the sausage, cabbage, and sweet potatoes. This is my husband's favorite soup.

• olive oil
• 2 cloves garlic, smashed
• one onion, chopped
• 1 package kielbasa, sliced—I get mine from a Whole Foods-type grocery (or 1 package of pre-cooked sausage like Aidell's Andouille or Trader Joe's )
• 1 small head of green cabbage (Savoy if possible), chopped
• 2 medium sweet potatoes or yams (orange flesh), peeled and chopped into large (1-2 inch) pieces
• 2 boxes Organic Free Range Chicken Broth
• 2-3 tbsps brown sugar (a handful)
• 2-4 tbsps apple cider vinegar (2-4 splashes)

Saute onion and garlic in a couple glugs of olive oil over medium heat until translucent. Stir often. Add sliced sausage and cook through (about 5 minutes). Add cabbage and sweet potatoes and all the chicken broth. Bring to a boil and reduce to a simmer. Cook until sweet potatoes are tender, about 15 minutes. Add brown sugar and vinegar to taste—make it as sweet and tangy as you like—a cook a further 10 minutes. Serve.
