In general bread is always present in the Tunisian table, and you will find mainly two types of meals, those eaten with bread, and others with spoon (or fork). This makes the presence of the knife, fork and spoon facultative for your plate, unlike in the occident culture where the only exception to their presence is sandwiches or maybe pizza.
You can think of bread-based meals as viscid broths, viscid in the way that it 's cooked long enough for the sauce to be thick and homogeneous, so you don't see water.
Two things will be almost always present in the list of ingredients: harissa and tomato paste. If you don't find harissa you can replace it in smaller amounts by chili pepper powder. As for the tomato paste, the replacement is to boil tomatoes, peel and then mash them, the amount will be twice as much as for the paste.
Here is a famous book of Tunisian recipes, it's in Arabic but like children you can look at the pictures :)
At the same time, I'll write detailed recipes of meals from time to time.
