I'd go:
sweet potato, cauliflower and broccoli curry (roast veg first for extra flavour!) with pan-fried sprouts (par boil, slice in half, fry in oil, add a sprinkle of lemon juice, cumin or cumin seeds, or a sprinkle of dessicated coconut if you've got it)
OR
Tagine:
oven roast sweet pot, cauli and broccoli and sprouts with oil, salt, pepper, dash of cumin/coriander, crushed garlic
meanwhile fry an onion, garlic, add can of tomatoes, pinch of cinnamon if you have it. Bring to boil and simmer for 10-15 mins until jammy/thickening.
When veg is nearly done mix the sauce into the tin and finish in oven.
Serve with crusty bread or couscous if you have it. You can pour a bit of plain yoghurt over it too.

if you have fresh coriander / parsley then that would be great to serve sprinkled over.
