Lentil and tuna Bolognese
Instead of a traditional meat-based sauce, the Bolognese sauce in this recipe is made with canned brown lentils and tuna, which makes a healthier, high fiber alternative to minced meat while still tasting 'meaty' and delicious. And rather than cooking the sauce slowly for hours until it’s rich and thick, we achieve the same velvety texture by thickening it slightly with a flour and oil roux so that it coats the pasta perfectly.
This sauce freezes well, so make it in big batches and freeze it in portions, then you’ve always got some ready to toss with pasta, layer in lasagna, stuff into cannelloni, pour over polenta, or serve on a baked potato.
