Crock Pot Stiffado

    1 tablespoon vegetable oil
    2 lbs. stewing beef, cut into 1-inch cubes
    3 large onions, peeled and diced
    4 garlic cloves, minced
    1/2 teaspoon ground cinnamon
    1/2 teaspoon ground allspice
    3 tablespoons red wine vinegar
    1 1/2 cups tomato sauce
    1 teaspoon white sugar
    1 bay leaf
    1 cup crumbled feta cheese

Heat oil in a skillet over medium-high heat and brown beef in
batches and, if necessary, adding more oil if needed. Transfer beef
to crock pot with a slotted spoon. Reduce heat to medium and add
onions to skillet, cooking until soft; add garlic, cinnamon and
allspice and cook for 1 minute. Add vinegar, tomato sauce, sugar and
bay leaf and stir well to combine. Pour mixture over meat.

Cover and cook on Low for 8 to 10 hours or on High for 4 to 5 hours,
until beef is tender. Add feta cheese, cover again, and cook on High
for 10 minutes. Discard bay leaf and serve over hot buttered pasta
or mashed potatoes.
