Last Update: March 27, 2026
Our Better Than Takeout recipe series is meant to inspire cooking at home—rather than falling victim to the expensive, unhealthy, and often time-consuming process of ordering in from a food delivery app. As an alternative, we’ve assembled a few recipes that we think are more nutritious (and certainly more affordable!) than takeout, and they take just a few minutes to prep and cook. From savory stir-fries to protein-packed meatballs and warming grain bowls loaded with veggies, these are the meals we hope you’ll return to again and again on busy weeknights.
Are you familiar with onigiri, a popular Japanese snack made of a ball of white rice wrapped in nori? It’s popular for a reason: it’s easy to make, easy to eat, and endlessly customizable, as you can choose to fill it with many types of fish, pickled vegetables, or sauces. This easy tuna onigiri becomes even easier when you fill it with canned tuna and microwavable sticky rice—in fact, the whole thing comes together in just 15 minutes!
