If I was to open a lunch wagon business ("roach coach") that offered short order sandwiches, maybe even burgers, and smoothies, and said it was "healthy" food, what items would you like to see on the menu?

I am actually interested in smoothy recipes *cough*JambaJuice*cough* and if anyone has any favorites, would you mind sharing the recipes?  

Basically, my friends and I are thinking of pooling our money and purchasing a lunch wagon vehicle, then loading it with a couple blenders and other implements of culination. I'll need to get a health license and other permits.

I am thinking of trying to park the wagon outside of the high school when school lets out (there are no smoothy restaurants in the area), and likely taking the vehicle around to different spots to see what will work.

I am leaning towards smoothies as a big part of the menu/draw. Sandwiches, various types of chips and fries, etc.

I want to lean towards BTD type menu items, and maybe even have a poster that if a customer wanted more info on eating healthy, I give them a flyer that explains the BTD and which menu items go with which type.

What do you guys think?

The only comment I have is that I'm not sure you can make smoothies fast enough to satisfy enough customers to pay for a truck...  
Food service is typically a low-margin business, but you need to write a business plan to see what pay-back you can expect...  
I wish you the best in whatever you decide...

Thanks for the encouragement....

if I were in the region,
I definitely would drop by for lunch!!!

I know there must be others looking for healthy fresh alternatives during work hours

Since I drink a smoothie everyday, I certainly feel positive about the idea.  I don't ever frequent the smoothie carts around here because they all have apple or orange juice as a base, which I don't drink, and strawberries as the primary fruit, which is too acidic for me.    Oh, everyone puts bananas in them, which are not good for me.

As a type B, I vote for pineapple juice base with frozen blueberries and yogurt as basic ingredients.  Ground flaxseeds and lecithin as optionals.  

I never trust smoothies that I don't make myself because I never know what's in them. Yogurt for a base would work for As, Bs, and ABs, but not for Os.  The only smoothies I ever eat contain spinach, raspberries, water, and stevia, and sometimes rice protein powder if I'm having it for a meal rather than a snack. And I make mine heavy on the greens with just a  bit of fruit- too much sugar in one meal is never satisfying to me.

I don't know if a green drink with just a hint of  berry flavor would be commerically appealing.
