What better way to enjoy a sunny day than with this easy keto meal: Fish with Red Pesto and Tomato, a recipe from my new book Low Carb on a Budget

The recipe truly couldn’t be easier to make, with just 3 main ingredients. Replace the red pesto with green pesto or olive tapenade for a fun flavor variation. It tastes amazing whichever way you prepare it: in the oven, on the barbecue or grill, or in a large frying pan.

Use local fish that is in season depending on where you live: hake, sea bass, cod, red snapper… If you’re a vegetable lover like me, feel free to add extra vegetables to the oven dish such as zucchini, fennel, bell pepper or onion. The fish with pesto tastes amazing with green beans or sugar snaps too, or just a large mixed salad during summertime.
