Oh goodness these are delicious! I love the hidden veggies in these too. You can vary what vegetables you use. I use whatever is in the fridge. They taste just as good without bacon too for a vegetarian option.
They can be frozen after baking and thawed. These are great warm or cold for kiddies lunchboxes.
