This dish is most likely going to be a side dish with a larger Greek feast possibly of spanakopita, souvlaki, potatoes and salad. But if you like this dish a lot you can just make more of it and have it as a main dish
Heat the olive oil in a pan. Once hot, add in the onion, garlic, cumin, and oregano
Cook the onions until they start to brown. Reduce to medium heat and add in the tomatoes, water, and beans. Cook for 15 minutes while constantly stirring
Transfer all of the ingredients into a lidded pot or casserole dish and place it in an oven at 150C/300F/Gas Mark 2
Leave the fasolakia to slow cook in the oven for approximately 40 minutes. The sauce will thicken and the beans will become soft and tender. Check and stir throughout the cooking process
Remove from the oven and squeeze lemon juice over the dish. (Ideally fresh, squeezed lemon). Sprinkle with salt and pepper for taste and drizzle a little olive oil over the top
