Heat the oil in a large pan, add the onion and cook for about 5 minutes until the onion starts to go translucent. Add in the garlic, stir and cook for a further minute.
Add in the rice and stir until the oil has coated the rice. Add in the wine and stir. Wait for the wine to almost fully absorb (stirring regularly) and then add the stock a ladle at a time - ensuring each ladle has almost fully absorbed before adding the next. Ensure you stir regularly.
After about 15 minutes you should have 1 or 2 ladles of stock left. At this point, add in the asparagus and mangetout. Stir and continue to cook for 5-6 minutes, adding the rest of the stock a ladle at a time.
Add in all but one tbsp of the parmesan, the lemon juice and salt & pepper. Give everything a good stir then turn off the heat. Stir through the mixed baby leaves, then divide the risotto between 2 or 3 plates. Top with tomatoes and radishes then spoon on the crème fraiche, followed by the pesto. Sprinkle on the remaining parmesan, along with the fresh parsley and some ground black pepper. Serve immediately.
