Cheese is non-negotiable. 

Between busy schedules and picky kids, weeknight dinners can make us want to crawl under the table. Our solution to calming the chaos? Making "modular" mealsones that can be adapted to all types of choosy palates.

In this week's episode of "Things Cooks Know," hosts and Real Simple editors Sarah Humphreys and Sarah Karnasiewicz discuss their modular meal of choice: the deliciously humble taco. Starting with the tortilla (Humphreys has a bias toward hard shells, Karnasiewicz prefers corn), they talk through each delicious layer—from the main event (which doesn't have to be meat!) to a surprising variety of toppings (sesame seeds, anyone?). They also answer questions from Real Simple listeners—and this week, it's all about how to salt your tacos.
