I have some ol' standbys when I make my sandwiches.
1. Toasted bread with garlic butter, add copious amounts of sliced chicken, alfredo sauce and parmesean cheese.
2. Sliced ham, turkey, bacon, pepperoni, cheese of choice, bbq sauce.
3. Pepperoni, ham, shredded mozzarella, pizza sauce (I prefer this with a flour tortilla)
4. Fried egg (or scrambled), sausage patty and a touch of maple syrup between two toaster waffles.
*NOTE* As you may have guessed by my recipes, I'm not much of a fruit/veggie guy. Add preferred amounts of plant matter to the recipes at your own preference/risk.
