In a skillet, heat olive oil and brown beef, salt and peppering to taste. Remove from skillet and set aside.
Add water to skillet, scraping up all the brown bits in the bottom of the pan.
Place vegetables in a large crockpot; add meat, then cover with the water from the skillet. Cover and cook on low for 8 to 9 hours or on high for 4 to 5 hours, or until veggies are tender.
