Preheat oven at 375 degrees.

In a large frying pan, saute the onions and mushrooms until lightly browned.

In a large saucepan of water, bring the green beans to boil until tender but crisp.

In a saucepan melt the cream cheese and thick cream until a smooth sauce is formed.

Add the sauce to an ovenproof dish with green beans, mushrooms and onions and stir well.

In a small bowl, mix the almond flour, minced onion and olive oil until it resembles breadcrumbs.

Sprinkle over the green bean mixture and bake for 20 minutes.
