One carrot, one big onion, some celery (you can skip it), when the veggies are nice and golden, i put some tomato paste, garlic and spices, after one minute i add 2 cans of rinsed red beans, and then one can of crushed tomatoes and 2/3 of that can in water, then an optional bouillon cube. Simmer until ready with a good consistency.
You can simmer it in some wine before the tomatoes like the real bolognese, but I don't drink wine so don't have any. Put in on rice or pasta or boiled potatoes, maybe polenta.
I'm from Ukraine, so it won't be really useful to reference prices, everything is much cheaper here. Regardless, costs 230 UAH (little over $5) to make but if I catch beans and tomatoes on sale it's even better. #finance source
