A weeknight spaghetti with harissa, tomato, and tuna: the spicy chili pasta Tunisian kitchens cook as ordinary food, not a national-dish stunt.

2. Build the harissa base: Warm the olive oil over medium heat. Cook the onion until soft, about 5 minutes. Add the garlic, tomato paste, and harissa; stir for 1 minute until the paste smells toasted and brick-red.

3. Loosen the sauce: Add the reserved pasta water and stir until the sauce looks glossy. Fold in the tuna so it flakes into the sauce without turning to mush.

## Storage
Refrigerate leftovers for up to 2 days. Reheat with a spoonful of water so the harissa sauce loosens.
## History Context
Tunisia adopted dried pasta through Mediterranean trade and Italian presence; harissa — a chili paste tied to Tunisian pantries after New World chiles reached the Maghreb — is what makes this bowl “cabai pedas” in Indonesian search language. The heat is the condiment history, not a 2026 fusion garnish.
