Healthy Green Bean Casserole

Bring a large pot of water to a boil.

In the meantime, trim green beans and cut them into 2 1/2 cm (1 inch) pieces. Put them into the boiling water and when the water starts to boil again, drain and rinse under cold water. Set aside.

Preheat oven to 180ºC (350ºF).

Heat oil and add mushrooms and onion. Cook until they turn light brown. Add white wine and continue cooking until wine has cooked off. Set aside.

Pour milk into a saucepan and add flour, gradually whisking all the time. Cook, whicking continuously, until sauce thickens (it will happen fast). Add mushroom-onion mixture, soy sauce (or tamari) and beans. Stir well. Adjust the taste with salt and pepper.

Lightly oil a casserole dish, transfer the mixture to the dish, and sprinkle panko on top. Bake for about 35–40 minutes until golden brown.
