I was at Publix and had the poor meat slicer read all of the ingredients of the Boar's Head deli meats. None of them were without sugar (to his surprise - he didn't want to check because it's "Crazy to think Organic Turkey Breast would have sugar." I asked nicely and he checked. Sugar in them all.
Applegate Farms has a couple that are compliant.

I pour it on top of my tuna when i eat it out of the can after my gym workouts.  it's one of the only things that helps me choke the tuna down besides home made mayo.  but i don't use the mayo after workout due to wanting to limit the fat intake after the workout.  

 
If vegetable oil is listed as an ingredient I would not use that mustard. I've never heard of such a thing. I'm sure you can find a mustard without it.

I don't worry about "natural flavor." When I am in a restaurant, I like to put French's yellow mustard on grilled chicken. I use something else at home, but like to smear yellow mustard on pork chops near the end of cooking.

Kombucha is typically very low in alcohol (it isn't made with alcohol, but alcohol can be a byproduct of fermentation). The kombucha you find in stores will be less than 0.5% alcohol content. Kombucha is also a natural fermented beverage that has been shown to improve digestion and gut health. Alcohol in this case is naturally occuring (similar alcohol levels can be found in fruit juice!)
 
Vanilla extract, on the other hand, is typically made by distilling vanilla bean in ethyl alcohol (alcohol is an ingredient in vanilla extract), typically about 35% alcohol or more. While vanilla is a nice flavor, it doesn't have any particular health benefits and it does not improve gut health. Those who want vanilla flavor during a whole30 can use vanilla bean or (unsweetened) vanilla powder. One could argue that the tiny amount of vanilla extract in a recipe doesn't matter, but the whole30 rules simply state that no amount of alcohol added as an ingredient in a product is acceptable.

Amber is right. We have refined our comments about kombucha over time. At first, I would not buy any GT Dave's product that listed more than 2 grams of sugar in the macronutrient report section, but the issue is added sugar, not the sugar from the original fruit ingredients. I still avoid the higher sugar drinks because I don't like them as much. I recommend avoiding the drinks like Guava Goddess because the sweetness may embolden sugar dragons, but they are officially acceptable. 

There is no sugar gram per serve recommendation - kombucha is ok as long as no sugar is added after fermentation.
If you're worried abou it, go for one without fruit/juice added

Hi all!
Before you create a new can I have, take a peek at this list we've compiled of the most common "Can I Have" questions!

This is GREAT. Really paints a clear picture of not only the WHAT can you eat/not eat but also the WHY.

As longs as you check the ingredients on their meats and dressings, a salad bar should  be okay. If there's anything there that sees to be canned, ask for ingredients for that as well.

Here's a recipe from Paleo Diet Lifestyle.
Ingredients

1 can (6 ounces) tomato paste;
2 tbsp vinegar or lemon juice;
1/4 tsp dry mustard;
1/3 cup water;
1/4 tsp cinnamon;
1/4 tsp salt;
1 pinch ground cloves;
1 pinch ground allspice;
1/8 tsp cayenne pepper, optional;

Preparation

Simply combine all the ingredients in a bowl and whisk well to combine. Refrigerate overnight to let the flavors develop and enjoy!

Back when I made meat loaf in my pre-paleo days, I added shredded carrots to the meat instead of bread crumbs and used salsa instead of ketchup. I just thought salsa was better than ketchup. Still do.
