Gruyere. Outstanding with this dish. It's that cheese you find on French Onion Soup.

A great appetizer or a main course. Pair with a simple green salad or some fresh tomatoes.

1. Over medium-high heat, caramelize the onions in 3 Tbs of oil.
2. When onions are almost ready, add the garlic, thyme and red pepper flakes, then season to taste with salt and pepper.
3. Mix together the eggs, cream and sour cream with 1/2 tsp salt and pepper.
4. Spoon some of the caramelized onions into the tarts then sprinkle with some of the chives and cheese then pour the egg mixture just below the top of the shells.
5. Bake at 400 degrees until egg is set - about 10-15 minutes

NOTES: You may have some onions, chives, cheese and egg mixture left over. That's alright. Just make another tart or two then you can freeze the finished tarts for another day.

NOTES: Use the egg mixture base as a springboard to your own tart masterpiece. Try adding bacon, spinach, sun-dried tomatoes or fresh tomatoes. Make it your own. I'll never tell where you got the recipe.

NOTES: For a larger tart that you can slice and serve: use an 8"-9" shell and bake a few minutes longer until set.
