Continuing on with the food holiday theme this month, and tipping my hat to National Hamburger Day on July 28th. How do you make a really great burger? Grind your own meat. How do you make it taste even better? Make your own hamburger buns. And how do you really take it over the top? Fill it with a little homemade pimento cheese and slather some of that delicious southern spread on the bun as well. That’s right, multiple recipes in this post for the ultimate summer grilling sandwich.
