Sweetpotato with bacon

Ingredients

2 lb. bright orange sweet potatoes (about 3 med.), peeled and cut into 2-inch pieces
2 Tbs. olive oil
4 oz. pancetta or bacon, finely diced
1 med. onion, coarsely chopped
1 Tbs. red wine vinegar
1/4 C. mascarpone cheese or cream cheese
3/4 tsp. salt
1/4 tsp. pepper
Directions

Boil sweet potatoes in large saucepan of boiling salted water over medium-high heat 15-20 minutes or until very tender. Drain; return to saucepan. Meanwhile, heat oil in large skillet over medium heat until hot. Cook pancetta 2-3 minutes or until beginning to brown. Add onion; cook 15-20 minutes or until onions are caramelized, stirring frequently. (Adjust heat, if necessary, to prevent onions from browning too quickly.) Add vinegar, stirring to scrape up any browned bits from bottom of skillet. Over very low heat, mash sweet potatoes. Stir in mascarpone, salt and pepper. Stir in onion mixture.
