I like sweet potatoes without anything, but once in a while I get one that doesn't seem to have much flavor/sweetness. When that happens, I add some orange juice. That seems to perk it up.
I use low fat buttermilk and chives in/on my mashed or baked potatoes. I also use plain, low or non-fat yogurt.
I use low-fat (1%) yogurt in place of sour cream.
I use olive oil and balsamic vinegar on roasted vegetables.
I also use lemon juice and pepper on steamed vegetables.
You can also brush bread with olive oil and bake it, making a nice toast.
I'd rather use regular butter than any margarine or butter-like substitute, and do so very occasionally.
Also, crushed pineapple is good on sweet potatoes.
