Egg & Pepper sandwiches are a favorite of mine, and you can really eat them at any time of the day. I heat some extra virgin olive oil in a pan, and toss in a little minced fresh garlic (don't use that awful pre chopped stuff in a jar, chop it yourself). I then add in some green bell pepper cut into strips (fresh is best, as opposed to frozen) and saute them a bit just until they start to become a little tender, but also still have some bite to them. Next comes the scrambled eggs that I seasoned with sea salt and fresh ground black pepper. Once the eggs are cooked through I put them onto a toasted crusty roll, and I will either eat this as is, or add some Parmesan/Romano or maybe even melt some Provolone over it, by putting it under the broiler for a bit.
If there are beef or pork roasts on sale at your grocery store, consider making your own "lunch meat" with them, by simply roasting them and slicing them really thin once chilled. For the beef, I would probably do a mayo/horse radish sauce to go along with it. For the pork, you can make Cuban Sandwiches, which are a crusty roll, with sliced roasted pork, deli ham, pickles, provolone cheese and spicy brown mustard. Assemble the sandwich then grill the whole thing until it's heated through and the cheese is melting. I like to put mine on my Panini press.
A grilled chicken sandwich is good too, if you slice up the chicken into strips and pour some sweet Thai chili sauce over it, and perhaps a cheese of your choice, like Mozarella.
