How to Make It
Preheat oven to 375°.
Combine oil, honey, and garlic in a large bowl. Add tomatoes; gently, with your hands, toss until thoroughly coated. Pour tomatoes onto a jelly-roll pan; turn tomatoes until they're all cut side down. Draw tomatoes together until they're cozy and touching. If there's any honey mixture left, drizzle over tomatoes. Bake at 375° for 20 to 25 minutes or until wrinkled and soft but not mushy; do not brown. (Note: Grape tomatoes may take less time than cherry tomatoes.) Remove tomatoes from oven; cool to room temperature.
While tomatoes cook, place farro in a medium saucepan; cover with water to 2 inches above farro. Bring to a boil. Cover, reduce heat, and simmer 15 minutes or until nicely chewy and not puffed open and starchy. Drain and rinse with cold water; drain.
Combine farro, tomato mixture, vinegar, and salt in a large bowl; toss gently to combine. Top with walnuts and feta; garnish with thyme. Serve immediately, or let the flavors marry in the fridge for an hour or
