How to Make It
Heat oil in a large nonstick skillet over medium-high. Add beef; cook 6 to 7 minutes or until browned, stirring to crumble. Add onion, turnip, carrot, rosemary, and garlic to pan; cook 6 minutes or until vegetables are tender, stirring occasionally. Whisk together stock and flour. Add stock mixture to pan; bring to a boil. Reduce heat to medium, and simmer 4 minutes or until thickened. Stir in peas, pepper, and salt.
Place potatoes in a microwave-safe dish; cover with plastic wrap. Microwave at HIGH 6 minutes. Add milk to potatoes; mash to desired consistency. Divide potato mixture among 4 shallow bowls. Top evenly with beef mixture.
