Grilled Cheddar Burgers - First Grill of the Season

This evening we fired up the grill for the first time this year. We kept it simple and fixed burgers. I purchased freshly ground chuck at Fresh Market this afternoon (it was on sale for $2.99/lb, normally $6.00/lb). I used 1 pound of beef and mixed it with 1 tablespoon each yellow mustard and organic ketchup (no HFCS). I also mixed in about 1/3 pound of shredded sharp cheddar cheese and then added a pinch of salt and few grinds of black pepper. I divided and shaped the meat into 3 one-inch thick burgers. After preheating the grill, I grilled them for about 5 to 6 minutes per side over medium-high heat, until they were medium-well but still juicy, then placed them on a plate and covered with foil until ready to serve.

I also sliced up a Vidalia onion and placed it in a foil packet with a pat of Kerrygold butter and seasoned it with salt and pepper, then placed the packet on the grill while the grill was heating up. I moved it to the side away from the fire while the burgers cooked. The onions turned out so tender they literally melted in your mouth. I sliced a tomato and steamed some fresh broccoli and in about 20 minutes from beginning to end, dinner was ready. I topped our burgers with a slice of Asiago cheese. It was simple, fresh and delicious. What is it about the first grilled burgers of the season that taste so good? I snapped a few photos below. Enjoy!
