For the casserole you see in these updated photos I used mushrooms and green peppers with two kinds of cheese. But see my suggestions for other tasty ideas for a meatless breakfast casserole using what you have on hand. And there are many options for cheese to use in a recipe like this as well, but personally I would always include Feta!<\/p>\n<p style=\"text-align: justify;\">Breakfast casseroles are always a great way to use leftover vegetables, and I think recipes like this are so perfect to make on the weekend and have a tasty breakfast to reheat during the week! And today is the first day of Lent, so this recipe is a great option for people who are looking for satisfying recipes without meat. But whether you&#8217;re avoiding meat or just someone who enjoys vegetables, I hope you enjoy trying this vegetarian breakfast casserole that&#8217;s loaded with cheesy flavor!<\/p>\n<p><!--more--><\/p>\n<h2>What ingredients do you need for this recipe?<\/h2>\n<p>(This is only a list of ingredients; please scroll down for complete printable recipe.
