Vegetable Tray Bake with Swiss Mushrooms – Grain and Dairy Free

Vegetable traybake with Swiss mushrooms as protein ingredient of the dish and egg batter with pumpkin seed flour, is an easy to prepare and nourishing meal. All you need is cook mushrooms with onions and add them to plenty of grated vegetables, carrots, pumpkin, zucchini as a base, with anything else you want to throw into the mix. To bind all ingredients  together during baking I used lightly beaten eggs with pumpkin seed flour, an excellent, protein rich dry product making grain free baking a breeze. The choice of spices and seeds to top the bake is up to your taste. Herbs and spice mixes or preserves can be added as well.

The dish can be served warm or cold. It can be frozen for longer than 5 days storage. Reheating it in the oven, or even in a frying pan with a lid without loss of taste and texture, makes it very handy in bulk cooking. This particular bake also served another purpose – to utilise overgrown zucchini and an abundance of cherry tomatoes from home garden.
