While researching some information on condiment packets I cam across this story about a person in Oregon who got stuck in a snow storm with is dog in his car and all they had was hot sauce packets from Taco Bell. Taco Bell Hot Sauce doesn't have any calories but at least its something to put in your stomach.
I found one entry saying a packet of Taco Bell Hot Sauce has 7 calories but it's other info, like daily Vitamin A, didn't match up with the other label data.
The main info on this page says there are no calories https://www.sparkpeople.com/calories-in.asp?food=taco+bell+hot+sauce
If you look on the side menu of other user entered label data one says "Taco Bell Hot Sauce Packet (1 serving)
Calories: 7, Fat: 0g, Carbs: 1g, Protein: 0g"
I'd think tomato paste, even a small amount, had some calories. One tablespoon of tomato paste has approximately 13 calories (https://www.nutritionix.com/food/tomato-paste).
