PREPARATION:
- Combine lamb, onion, water and garlic in large saucepan. Bring to a simmer over medium-high heat. Cover and simmer 30 minutes. Increase heat to high and uncover. Bring to a boil, stirring occasionally, until liquid evaporates. Add tomatoes with juice; stir. Reduce heat to medium-low; cover and simmer 30 minutes.
- Meanwhile, cut potatoes into 1-1/2-inch pieces. Add potatoes, chiles, rosemary and oregano. Cover; simmer 20 to 30 minutes or until potatoes and lamb are tender.
- Halve zucchini lengthwise and cut crosswise into 1/2- to 3/4-inch pieces. Add zucchini and corn to stew. Cover; simmer 10 minutes or until zucchini is crisp-tender. Season with black pepper. Garnish with jalapeños, if desired.
