I make a lot of spice rubs from scratch so that I'm certain there is no sugar and I can reduce the salt.
Once the spice rub is mixed up, I keep it in a sealed tuperware container next to the stove so that I can season my proteins and veggies with it.
Fresh chopped herbs (rosemary, basil, thyme) from the garden are also fantastic ways to add favor to boring lettuce.
