1. Peel the carrots and turnips. Cut the tops off the spring onions. Rinse all the vegetables, cut the carrots and turnips into small pieces. Remove the core of the onions and cut them into quarters. Cut the turkey fillet into cubes of about 1.5 cm.
2. Drain the white beans over a container to collect the juice. Mix the juice with the tomato paste and 3 tablespoons of water, season with salt and pepper. Place the pieces of turnips and carrots in a bowl, add ⅓ of the sauce, mix well.
3. Place the turkey in another bowl with the spring onions and white beans, add ⅓ of the sauce, mix. Let these 2 mixtures marinate in the refrigerator for 1 hour, stirring occasionally.
4. Bring water to a boil in a saucepan. Once boiling, add salt to the water and add the green beans, cook for 8 minutes until they are al dente. Drain and set aside. Bring water to a boil in the lower part of a steamer. Place the carrots and turnips in the basket, cook for 10 minutes from the boiling point. Then add the chicken and spring onions, mix and continue cooking for 10 minutes. Add the green beans and the remaining sauce and cook for 3 minutes.
5. Pour everything into a casserole dish and heat over very low heat for 5 minutes so that the ingredients absorb the sauce well. Serve hot, sprinkled with chopped parsley and seasoned with a hint of chili.
