What is actually on the burgers? Front cover shows cheese & onions I think

Each burger has a slice of cheese and grilled chopped onions.

Will White Castle sliders cook in a regular toaster oven?

I’ve never tried to cook them in a toaster oven, I find that following the instructions on the box for cooking them in the microwave oven makes them come out perfectly. I kind of think that cooking them in a toaster oven would make the hamburger buns too hard, I’m just saying. Hope this helps you. They are very delicious.

How do these hold up if you microwave in the morning, wrap in foil, and eat at lunch? We've done this with hot dogs.

You should pack them in a lunchbox frozen and microwave it at lunch if you have a microwave available in where you eat lunch.

Would these cook decently in the microwave? That's all we have at work, and these seem great to bring in my lunch.

Yes. Put them in your freezer. In the morning, grab a pack and go. Place them somewhere safe. By lunchtime, they should've defrosted. You can either open one side of the package to vent and microwave for 35 seconds, or remove them from the package, put them on a napkin or paper towel an microwave for 30 seconds. When you open the microwave, put a finger on the center of a bun. If it's still cold, add 10 more seconds. There's only 3 packs per box, so I suggest buying 2 or more boxes if you want to last a week. Also, they're cheaper and fresher from grocery stores.
