Slice the broccoli florets in half and steam for 3 minutes. Add the peas to the steamer and steam for a further 2 minutes (or boil the veg for a few minutes if you do not have a steamer).
In a bowl, mix the olive oil, pesto, garlic powder, dried mixed herbs, salt and black pepper.
Drain the pasta and vegetables and add back into one of the pans.
Pour the olive oil sauce over the pasta and stir through on a low heat, until warm.
Finely grate the parmesan.
Serve the pasta with the parmesan and fresh basil over the top.
