Nasturtium pesto might sound a bit strange, but if you like the slightly bitter taste of nasturtium leaves (or rocket/arugula, if you’ve never tasted nasturtium leaves), you’ll love it. In fact the basic recipe is very similar to that of traditional basil pesto, only we’re varying the leaves.
Traditional pesto can be pricey though, which is not surprising given some of its original ingredients – parmesan cheese and pine nuts, neither of which is particularly cheap. Luckily, you can create something that tastes quite similar using more reasonably-priced ingredients, in this case, cheddar cheese (leave this out if you want a vegan or pure paleo version) and toasted sunflower seeds.
