It's the simple foods that make summer weekends perfect. The ham and egg sandwich is portable, savoury, and it's as easy to make one as it is to make a dozen. You can add some arugula and use two pieces of bread for a classic sandwich or serve them open face on the back patio with a side of pickles. Use the best ingredients you can find and don't try and complicate it – not even with mustard. It really works perfectly just as it is.
