Grilled Avocado, Tomato & Onion Sandwich

Today’s post is a salute to the ever popular sandwich! A sandwich, sammich, or even the Rachael Raysim – sammie, everything tastes better between two pieces of bread. From the simple peanut butter & jelly, to the complex Dagwood, sandwiches are a mainstay of our diets. Sandwich creators are breaking new grounds every day! Would you have thought of using a donut as a hamburger bun? I wouldn’t have. That’s probably a good thing. Take a look at the sandwiches listed on the menu of your favorite eatery. There’s double this or triple that, resulting in a sandwich that is a big as your head! You would have to have a flip top mouth to eat it! Stay away from those double or triples and make this sandwich at home. Save some money and have a delicious, good for you, meal in minutes.

It’s sammich time:

You’ll need 4 ciabatta rolls, or any sandwich roll, a couple of avocados, a red onion (because it’s prettier than a yellow), a big tomato, some mayo and some provolone cheese. Applegate is vegetarian friendly. As always, you can use what you have on hand. Maybe a spicy chipotle mayo and a pepper jack cheese, uh-huh!

Now, if you happen to be a grill master, fire up the barbeque and grill everything outdoors. Otherwise, get out your grill pan, large fry pan, or George Foreman grill and get ready to grill. We want a medium heat, so that everything cooks without burning. Pour a couple of tablespoons of olive oil in a dish and get out a  pastry brush. If necessary, slice the ciabatta rolls in half. Brush a little olive oil over the insides of the roll

and place them face down on your grill pan.

While they’re getting toasty, Slice all the veggies into 1/2 inch slices and spread the out on the cutting board or platter. Check the rolls. Are they nice and toasty?
