If you are worried and want to at least get an idea of what you think before you go, buy a can of Campbell's French Onion soup and try this easy recipe from the food website:
Ingredients
1 (10 1/2 ounce) can Campbells French onion soup
1/3 cup water (optional)
1/2 cup croutons
1 slice provolone cheese
Directions
Heat the soup on the stove or in a bowl in the microwave. Add croutons. Top with cheese. Let cheese melt. It's that easy! Enjoy!
*Or after topping with cheese you can put it under the broiler for a few seconds in an oven safe bowl if you want the cheese browned*
You can always forget the bread and cheese and just heat the soup up and taste it too.
Of course the Chefs version will be a million times better, but at least you would be able to decide if has an appetizing texture to you or not.
