I have put this recipe under spinach though you can use any cooked green or a combination based on what you have on hand including mustard greens, turnip greens, kale, swiss chard, etc.  Get creative!

3-4 TBLS cooking oil
½ cup minced leeks (cleaned) or onions
Optional herbs/spices like minced garlic, rosemary, thyme, etc.
1 cup of cooked greens (spinach or kale)
1-2 cups chopped boiled or roasted root veggies (carrots, potatoes, turnips, etc)
Salt and pepper to taste

Heat oil in large skillet or pan over medium-high heat. Sauté leek or onion for several minutes until well softened. Add cooked greens and roots and optional herbs, and sauté another several minutes until everything is hot and beginning to brown slightly. Season to taste and serve hot. A great accompaniment to eggs on a Sunday morning with ketchup or salsa!
