In a large, wide pot on medium to medium-high heat, combine olive oil, shallots, garlic, hot pepper flakes and sea salt. Cook, stirring often, until shallots are soft. Add tomato paste and allspice, if using, and cook until the tomato paste darkens in colour, about two minutes. Stir red wine vinegar into pan and cook for about two more minutes until some of the vinegar is reduced.
Pour in the tomatoes and bring to a boil. Reduce heat to medium low and simmer tomatoes until the liquid is reduced and the flavours are combined, about 7 to 10 minutes.
Add beans and stir gently. Cook until beans are warmed through, about 5 minutes. Season to taste with salt and pepper.
Divide spinach among four bowls or place on the side of a serving platter and pour beans on top of spinach.
Top with crumbled feta and dill.
