Quinoa Mac N’ Cheese

I found this recipe on Pinterest and I intend to try it at some point:
(I've simplified the recipe for my own use)

Serving Size: 6-8

Ingredients

2 tsp olive oil
1 onion chopped
1/2 cup tomato chopped
1 1/2 cups quinoa, rinsed and drained
good pinch of salt
a few grinds of seasoning salt
2 cloves garlic, minced
3 cups of water (or stock)
2 large eggs
1 cup milk
1 1/2 cups grated Cheddar cheese
Optional- Bread crumbs for topping


Directions

Heat oil, add onions and tomatoes. Stir in quinoa and garlic.  Add 3 cups water (or stock) and season with salt and the Seasoning Salt ( Lawry's or Everyday Seasoning). Cover and simmer 15-20 mins until most liquid has been absorbed. Remove from heat and let stand 5 mins.

Preheat oven to 350 F. Line 13x9 inch dish with parchment paper. Whisk together eggs and milk in large bowl. Fold in quinoa mixture and cheese. Stir very well and let some of the cheese melt.

Transfer to prepared baking dish and if using Bread crumbs, add now. You can also sprinkle a bit more cheese on now if you prefer for topping. Bake 25-35 mins, (or until browned around edges.)
