Syrups change the texture a little bit so if you don't mind it's ok. But the best SF syrup I have found are Davinci. They make tons of SF that don't taste so "diety" and they are really spot on.
Besides the best thing ever, they are Protein and veggie based noodles. The whole package is 12oz give or take and if you ate the whole thing it's only 50 cals and 2 grams of protein. The brand I use is Pasta slim. I get the spinach kind and make a Greek yogurt& laughing cow wedge "sauce" and it's delish! It's gluten free and I think that's the trick.
Try vanilla powder in your plain NF Greek yogurt. It adds all the flavor none of the alcohol taste from vanilla extract. Add some splenda for sweetness and you have low sugar/carb/cal deliciousness
You can try grilled veggies and cottage cheese. With Mrs. Dash you can't really go wrong. Or miracle noodles with veggies and a little sauce. They are awesome tasting, quick to make and they have great nutrition facts. A little goes a long way for bandsters. They come in different favors which is really cool too. Good luck ???Š
