Preheat oven to 450
In a large bowl, mix together the avocado oil, 2 lemons juiced, 1 1/2 lemons, zested (reserve the other half zest for later), salt, pepper, tarragon (reserve 1 tbsp for later), and garlic.
Add the green beans into the lemon mixture and toss well. With tongs, add the green beans onto a large baking sheet. Be sure to reserve the liquid.
Add the fennel and leeks to the lemon mixture and remove it with tongs and place on a baking sheet.
Then add your chicken cutlets to the lemon mixture. Mix well and place onto the baking sheet with the veggies
Add the other 1/2 of that lemon zest, fennel fronds, tarragon, and a dash more of salt and pepper
Roast everything for about 20 minutes or until chicken is cooked through.
Serve with potatoes or rice or just as is. Enjoy!
