The color red can cause problems, like when red sauce gives you heartburn, or red roses unintentionally tell a girl that you heart her, or you're just gored by a bull. Foregoing red (tomatoes) for yellow (tomatoes): Yellow Belly Food Truck.
From a trio including Cordon Bleu grad and Four Seasons vet Jason Tolleson, Belly's concept originated from a yellow tomato salsa entered into a competition a decade ago. Turns out, yellow tomato sauces provide a compelling sweetness, and their low acidity reduces heartburn risk even when you're chowing down on sammies like the Yellow Submarine (meatballs w/ yellow marinara, smoked provolone & goat cheese on a bolillo roll) and the BLYT: sourdough stuffed w/ fried yellow toms, leaf lettuce, and candied bacon -- drop a chunk on the ground, and whoever spots it will ask "whose hairy crumb?".
Bypassing bread, there's a smoked brisket link w/ yellow BBQ sauce, pear & jalapeno slaw, and Tabasco'd onion rings, and yellow-sauced pork wings called Flying Swine, though you shouldn't wait 'til that happens to order it. Liquidly, go for tea poured over cubes made from lemonade (or more tea), or the blueberry fojito mocktail -- if a cop asks if there's alcohol in it, just say "there isn't, no bull".
