Just flour and eggs: that's all that's needed to make perfect homemade pasta. Cut out any shape you prefer, and then with the leftover dough make "maltagliati" to add to your minestrone. Maltagliati are traditionally made from the scraps when making pasta and differ in size and shape.
Italian 00 flour is a very finely ground flour, which gives pasta a very smooth texture. Replace it with plain flour if you cannot find it; the texture will differ slightly and you may need to add a bit more water to achieve a smooth dough.
