There are two things which come to my mind - tomatoes/sauce and (red) bell peppers. I love both of their taste and they are good to have in your diet and healthy for you.
Besides being low in sodium, tomatoes are a good source of vitamins A, B6, C, K, folate, potassium/magnesium, sat. fat, cholesterol and more.
I love bell peppers of any color! A cupful is only 45 calories and daily quota of vitamins A , B6, C, E and lutein. They are antioxidant, control diabetes and lower cholesterol.
