If you want a preparation technique that deceivingly tastes like you've spent all day in the kitchen, try broiled Parmesan tilapia. It's quick, filling, and you won't have to feel overly guilty about eating it if you're calorie counting.
In terms of simplifying the ingredient list, you can substitute sea salt for celery salt and can nix the onion powder as well. The Parmesan and basil are prominent enough flavors that you can easily forgo some of these other additional seasonings.
My favorite thing about this recipe? It gives me that same warm, happy feeling that homemade mac and cheese or buttery mashed potatoes provide, without the extended prep steps and high-fat content that usually define comfort foods. Hey, when you love to indulge in food as much as I do, you almost have to have a least one healthy go-to comfort food.
