88 All-Time Best Dinner Recipes

Excellent recipe. But because I'm a lazy cook and didn't wanna deal with an hour of a propane cooktop burner going (the time, cost, AND the fumes), I used frozen caramelized onions that I get in the frozen section at Target. They come in what looks like a mini ice cube tray and they've been fantastic in every recipe in which I've used 'em. I still cooked it on the stovetop per directions, but it was 10 minutes of sauteeing versus 50. I cut the mayo in half (used vegan mayo) and used light sour cream in place of full fat. I added a 1/2 teaspoon of the beef version of Better than Bullion to give it color, and reduced the salt a bit to compensate, since BtB is very salty. This was a huge hit in my house! Thank you for this great recipe!

May I substitute Stevia for Splenda?

I also added sliced onions and zucchini and it came out amazing. I also added a little bit more butter and sprinkled water all over before sealing it with the foil.
