Halal cooking question for my friend

Salaam! I've got a Muslim friend who is always so kind, sharing tasty homemade meals with me. Cooking is my way of showing love, and I really want to cook a nice halal meal for her too. Thing is, I'm from a British background and we use all our pots and pans to cook non-halal stuff pretty much every day. Is there a way for me to still cook something safe for her to eat?
