Blend jicama with half the olive oil. Then stir in the garlic, rosemary, thyme, and salt. Spread out on rimmed baking pan.
In a bowl, mix the green beans with the remaining olive oil. Combine with jicama on baking pan.
Bake at 400°F for 45 minutes, stirring the vegetables every 15 minutes. Serve immediately.
Notes
If avoiding legumes, use asparagus in place of the green beans.Use a rimmed baking sheet. This prevents the food from accidentally falling off the side.
