What Else You Should Know
Rinse quinoa well under cold water to remove the natural bitter coating (saponins). Use 1 cup uncooked quinoa to 1 3/4 cups water or broth to yield about 3 cups cooked quinoa, exactly what you need for this recipe.
For quicker prep, use bottled lemon juice, pre-crumbled low-fat feta, and prewashed spinach. It can speed up the preps by 50%!
Choose tuna that’s water-packed and no-salt-added for a healthier option.
Pick a slightly firm avocado so it keeps its chunks; toss avocado with a little dressing or lemon juice to slow browning.
And it stores well in the fridge for up to 5 days.
Conclusion
Quick to assemble, great for meal prep, and easy to adapt—this bowl makes healthy lunches feel celebratory.
