11 July - fresh tuna with salsa verde and homegrown beans

The veg on the roof terrace are still flourishing; the mangetout are, I think, coming to an end now, so I picked what will probably be the last decent picking, with a few starting to get a bit overlarge and misshapen. The beans are coming along though and even though the dwarf French bean plants have never really got going, they're still managing to produce some decent-sized beans on really pathetically weedy plants! The climbing beans look much healthier, now reaching up to the top of their canes and producing their first handful of beans too.

To go with the veg, I had in mind some kind of fish with a variation on salsa verde, to use up some more of the parsley, which is starting to take over. Again, I wasn't very inspired by the fish on offer, so ended up with a couple of tuna steaks, which wasn't really what I had in mind, but actually worked okay. For the salsa verde, I whizzed together in a blender:

• a large bunch of flat-leaf parsley
• a small handful of mint
• a good tsp smooth Dijon mustard
• a couple of anchovy fillets
• a good glug of extra virgin olive oil
• juice of half a lemon

Very green and tangy dolloped over the tuna steaks.
