If you don't have a steamer head to "Our Store" and check out the Optimum Thermocook.
Its amazeballs and I would be without it. It steams veggies on a timer, ste and forget. once complete plate up and add some dried shallots and freshed seared garlic.
The fennel will be done simply plate it up and drizzle tiny bit virgin olive oil, salt and pepper on everything for taste and WALLA a meal as easy as u like healthy and packed with flavour.
By the way for extra flavour fresh mint and peas is delicious.
