You already own the data you need. One month of sales tells you exactly which items to push, re-price, fix, or kill — and the changes usually pay more than a busier Saturday.

Pull a month of sales and build one table. For every item, you need units sold and contribution margin in dollars — the price minus what it truly costs to hand over, including protein by the ounce, the packaging, the ramekin of sauce, and the napkin. Margin percentage misleads here: a 70% margin on a $4 side that sells eleven times matters less than a 55% margin on a $12 plate that sells four hundred times. Dollars per item, multiplied by units, is the number that pays you.
If your ordering system already tracks per-item sales, this is an export rather than an exercise. If it does not, that is itself a finding — you are running the most important decisions in the business on memory.
A truck menu has a constraint a restaurant menu does not: the window. If you serve 45 tickets an hour and could serve 60 with a simpler board, that is a 33% raise that costs nothing in ingredients. So time your items. Stand with a phone during a real rush and record how long each item takes from call to hand-off.
The rule that holds up: roughly 80% of the work should be prepped at the commissary, about 20% finished at the window. Sauces, slaws, braises and smoked meats travel well; searing, assembly and garnish happen live. Any item needing more than three live steps will break your line at a festival. Simplify it, or move it to catering where volume is known in advance.
Most customers choose while walking up, reading from about ten feet away. That constrains the design more than taste does: one hero item at the top in the largest type, five to nine items total, a combo that answers "just give me the usual," prices clean and in quarters, and no item that needs explaining. If a name needs a paragraph, rename it. Anything a customer has to ask about is time your line does not have, repeated all day.
The reason most menu changes teach nothing is that owners change five things at once during a busy month and cannot tell which one worked. Change one variable, hold it for two to four weeks, and compare against the same period before. Keep a simple log: what changed, the date, and the units and margin before and after. Seasonality will lie to you otherwise — a price rise in May will look brilliant regardless of whether it was.
Sort every item by units sold and by margin in dollars, then act on each quadrant: feature the popular high-margin items, re-cost or re-price the popular thin-margin ones, reposition or rename profitable slow sellers, and cut the items that are both unpopular and unprofitable. Most trucks find several points of margin without touching a headline price.
Five to nine. Below five, you lose customers who want an alternative; above nine, decision time at the window climbs and your prep and waste climb with it. If your board is at fourteen items, the fastest profit improvement available to you is usually deletion.
Raise selectively, not across the board. A small increase on one popular item you know is under-priced against its food cost is nearly invisible to customers; an across-the-board rise is noticed immediately. Re-cost your top three sellers whenever a supplier invoice jumps, and price in quarters to keep the window fast.
