Tomato and oregano Sweet Potato Gratin

Prep everything first: chop the aromatics, measure the tomato and oregano elements, and pat the sweet potato dry so it colours well.

Warm the olive oil in a large pan over a medium heat and soften the onion and garlic until sweet and translucent, about 5 minutes.

Add the sweet potatoes and stir-fry until it takes on colour and the edges catch, 4 to 6 minutes.

Stir in the san marzano tomatoes and the rest of the tomato and oregano flavours, letting them cook out for a minute until fragrant.

Add the broccoli along with a splash of stock or water, then cook briskly until everything is tender and the sauce clings.
