Heat the olive oil in a medium pot or Dutch oven with a tight-fitting lid over medium-high heat.
Add the onion, garlic, and bell pepper.
Cook, stirring occasionally, until the onion has softened, about 5 minutes. 2.
Pour in the chopped tomatoes, vegetable stock, and sherry (if using).
Add the bay leaf, a generous pinch of salt, and several grinds of black pepper.
Bring the mixture to a rolling boil. 3.
Stir in the rice and the drained chickpeas. Give it one good stir to combine everything, then reduce the heat to low. 4.
Cover the pot and let it simmer gently until all the liquid is absorbed and the rice is tender, about 20 minutes. Avoid lifting the lid while it cooks. 5.
Remove the pot from the heat and let it stand, covered, for 5 minutes.
Remove the bay leaf, fluff the rice with a fork, taste, and adjust seasoning if necessary.
Serve warm.
Don't be afraid to experiment with spices!
Add 1 tablespoon (15 ml / 0.5 fl oz) of curry powder, garam masala, or smoked paprika along with the onions for a completely different flavor profile.
