Looking for an easy lunch you can prepare ahead of time? This Fiesta Quinoa Jar Salad layers chicken, quinoa, black beans, corn, tomatoes, jalapeños, and spinach with a simple seasoned dressing for a filling, portable meal.
Mason jar salads are especially convenient for meal prep because you can prepare several at once and keep the ingredients layered until you’re ready to eat. This recipe makes one 1-pint (2-cup) Mason jar and can easily be scaled up to prepare multiple lunches.
The quinoa is tossed directly with the dressing before the remaining ingredients are layered into the jar. When it’s time to eat, simply serve the contents over the spinach and toss everything together.
This recipe was adapted from the Fiesta Mexican Quinoa Salad-in-a-Jar featured in Quinoa Salad-in-a-Jar in 4 International Flavors.
The nutrition information below is calculated for one complete jar as prepared. If you change ingredient quantities or make substitutions, remember that the calories and macros will change as well.
