It’s time! We need to talk quick and easy meals and let’s think outside the box!

Not every meal has to be from a crock pot to be “easy” and “quick”.  Don’t get me wrong. I love my crock pot! However, Summertime is the perfect time to have “low stress” easy meals.

Example: Yesterday for Sunday dinner we had grilled chicken breast. I marinated them in a bag with my favorite Kraft dressing. I made the Parmesan garlic butter red potatoes to go with it and a salad. Boom! Dinner! It was fast, quick, delicious and everyone raved about it!

Roast Beef Grilled with Cheese

Another simple “outside of the box” meal… how about this Roast Beef Grilled Cheese Glider? That’s right, a mile high hot sandwich for dinner! Think of it as Mr. Hamburgers country cousin!

 One of my girl friends boys named this sandwich! (I love the “glider”…this is for sure a glider and not a slider!) There should be a warning label attached to this sandwich! After you have it…you’ll be dreaming about having it again for days…maybe even weeks!

The beauty of this? This masterpiece sandwich is going to take you less than 25 minutes to throw together!

Start out slicing some red onion (it’s all I had on hand and boy am I glad) and some of the mini sweet peppers. You can find the peppers at Wal-Mart. They sell them in a bag for about $2.88! Deal! (I’m absolutely in love with them!)

Place them all in a skillet over medium heat with 1 Tablespoon of butter and caramelize them!

I want you to see the difference between the two…above is raw and below, is caramelized. So beautiful. You can see the sweet sugars released from those peppers and onions. They are the “star” of this sandwich!

While you are busy stirring those peppers around and making them beautiful, you can place your sliced roast beef in a small skillet to warm up. We aren’t really cooking it, we just want it warm for the sandwich. I purchased this roast beef from the deli and had them slice it sandwich slice. (Love those deli ladies…they work their fannies off!)

Once you have your peppers and onions all ready, you are going to get the “grilled cheese” portion of this sandwich going.

I used the Sara Lee Artesano bread for these sandwiches. (I have a carb crush on that bread!) It’s almost like having this sandwich on a gigantic savory soft crouton!

Butter the outside of each slice of bread and then place it butter side down on the griddle. On one half place mild cheddar cheese on the other half, one slice of muenster cheese and one slice of pepper jack. You can use what you have on hand but, I highly recommend the muenster!

Grilling cheese

Once your cheeses have melted, about 4-5 minutes,  it’s time to pile these sandwiches a mile high!

Prepare the mustard pepper spread and slice up some avocado.

On one half spread your mustard pepper spread, on the other half pile your beef, peppers and onions, and avocado.

Now is when your mouth starts watering! lol… Next you place the top on the bottom. (The top is the one with the spread…just in case you were wondering!) 

TIP: With the melted cheese on the top and the bottom, the sandwich is going to stick together really well. Which is good cause, you don’t want to loose those peppers!

I wish there was “taste-a-blog” so that you could take a bite out of this incredible sandwich!

The combinations come together to create one amazing taste sensation! The tender juicy roast beef with the sweetness of the caramelized onions and peppers followed by the creaminess of the cheeses and avocado and then the mustard pepper spread! All inside this amazing buttery crispy Artesano bread! Ahhhh…(sigh)…perfection!

In case you think I’m tooting my own horn a little too loudly, and I probably am, Mars said “On a scale of 1-10 this is a 12!”

 This is the “Real” Manwich!  Throw in some fresh fruit and a side of chips and you have a quick, delicious, mouthwatering, summer dinner! Best part…no silverware needed!

I hope you enjoy making this recipe as much as I did creating it!
