1. Celery and Apple Salad: Start by combining diced celery, apples, and a handful of almonds into a large bowl. For the dressing, mix together some fresh lemon juice, extra-virgin olive oil, and honey. When ready to serve, drizzle over the salad and toss until everything is evenly coated.
2. Creamy Celery and Leek Soup: Soften some leeks in butter, then add diced celery, potatoes, and chicken or vegetable stock. Simmer until everything is tender and puree with an immersion blender for a creamy texture. Season to taste with salt, pepper and nutmeg.
3. Roasted Celery with Parmesan: Cut celery into bite-sized pieces, toss in olive oil, and spread onto a baking sheet. Roast at 375F for 20 minutes until golden brown, then sprinkle liberally with grated parmesan cheese and return to the oven for an additional 5 minutes.
4. Fennel and Celery Salad: Combine thinly sliced fennel, celery and radish with a dressing of your choice. A creamy tahini-based or yogurt-based dressing work well to bring out the flavors in this salad.
5. Celery Stuffed Mushrooms: Stuff a mixture of diced celery, garlic, onion and herbs into mushroom caps. Drizzle with extra-virgin olive oil, season to taste and bake for 20 minutes in a preheated oven at 350F. Serve as an appetizer or side dish.
