Preheat the oven to 350 degrees. Beat 3 eggs and mix them with 1/2 cup of Bisquick, 1/2 cup melted butter, 1 1/2 cups milk, 1 cup of grated Cheddar cheese, 1/2 teaspoon chopped thyme, a pinch of salt and a sprinkling of pepper. Add 1/2 a cup of chopped ham. Pour the mixture into a 9-inch pie plate and bake your quiche for 45 minutes.
Bacon is a good substitute for ham, but if you prefer a meat-free version, chop up some mushrooms and onions instead. Not only is this quiche wonderfully quick and easy to make, but it's also customizable. If you don't have Cheddar cheese, Swiss works just as well. Feta gives a creamier result, while blue cheese is beautifully rich.
Other vegetables that work well are leeks, green or red peppers or broccoli, which works especially well if you've chosen blue cheese.
This quiche is a great way of using leftovers, such as ready cooked butternut, asparagus or eggplant. If you have leftover chicken, debone and cube it for your quiche. Firm, flavorful fish such as salmon and trout work well. Just be sure to get rid of any bones before flaking the fish and adding it to your mixture.
Flavour combinations that work well are bacon and onion, chicken and leek, blue cheese and broccoli, salmon and asparagus, and butternut and onion. If you don't like thyme, use oregano, dill or parsley instead.
Remember to let your quiche set for 10 minutes after you've taken it from the oven.
