20 Easy Vegetarian Casserole Recipes for the Whole Family

Given the choice, I will always choose the vegetarian casserole over the meat one. Which is surprising since I am a butcher’s daughter and grew up with meat on the table 6 nights a week. I’m not sure my dad knew how to make a meal without meat unless it was salad night – which would then be a bevy of mayonnaise-laden salads.

My parents had huge health issues.

Meat is great for protein, but so are grains and legumes! Give me some chickpeas over a hamburger any day.
