In the meantime prepare the asparagus: Pour some boiling water in a frying pan and add the asparagus spear halves. Cook for 5 minutes then drain and reserve.
Use the same pan to heat up one tablespoon of oil.
Add the garlic and after 2 minutes add the breadcrumbs. Stir to allow the breadcrumbs to soak up the flavour. Continue to cook until slightly brown.
Return the asparagus to the pan to cover with the breadcrumbs garlic mixture.
Serve the asparagus with the cooked fish. If liked you can also include saute potatoes which can be prepared within the 20 minutes while the cod is cooking in the oven.
