Tomato, Squash and Red Pepper Gratin

Tomato, Squash and Red Pepper Gratin

By Taking On Magazines

With a simple sauté all things vegetable (except the potatoes), you're ready to go. Veggies, quinoa and a milk/egg mixture get swished together and dumped in a dish, then topped with toasted bread crumbs (I used a spoon).

Easy enough work for a vegetarian dinner.

It's very tasty. I like the combination of vegetables, the garlic, cheese and especially the quinoa. In fact, I wish there had been more of the latter instead of egg involved.

  • 5 tsp olive oil, divided

  • 2 cup chopped red onion
