Tuna is a high-quality protein that is low in fat and full of essential amino acids that the body needs for growth and maintenance of lean muscle tissue.
This flavorful and healthy Mediterranean-inspired fish dish is ready in less than twenty minutes and is a delicious healthy meal for the summer months.
It features Italian gremolata – a simple green condiment made from a combination of fresh parsley, garlic, and lemon zest. This version also incorporates a nod to Moroccan cuisine with the addition of preserved lemon rind for a bit of extra flavor and visual interest.
What is Gremolata?
Gremolata is a green sauce made with just three ingredients – fresh parsley, lemon zest, and garlic. It is the standard accompaniment to the Milanese dish Ossobuco alla Milanese. Gremolata is also used as a garnish to top meat, poultry, seafood, and vegetables.
In this recipe, we’ve used preserved lemon rind for an added pop of flavor.
Preserved lemons are made by curing the fruit with salt. The sharpness of the citrus mellows, but the flavor intensifies and can add such a depth of flavor to dishes. Preserved lemons are a staple ingredient in Moroccan and North African dishes.
You can buy preserved lemons in jars in grocery stores, delis, or online. And you can actually make your own too!

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
