We love it when you customize our recipe and make it fit your home, culture and body. Except, honey, French toast isn't meant for your body. It won't be as wholesome with low fat as it would be with whole milk, and any other oil just won't sizzle the same. We'd suggest you use a combination of oil and butter to prevent the toast from burning, but we hope you won't skip it altogether. However, suppose you're making a savoury version of this without the sugar. In that case, you can definitely add some cheese and make it somewhat nourishing.
