An insulin index of foods: the insulin demand generated by 1000-kJ portions of common foods: http://ajcn.nutrition.org/content/66/5/1264.full.pdf
The results of this study confirm and also challenge some of our basic assumptions about the relation between food intake and insulinemia. Within each food group, there was a wide range of insulin responses, despite similarities in nutrient composition. The important Western staples, bread and potato, were among the most insulinogenic foods. Similarly, the highly refined bakery products and snack foods induced substantially more insulin secretion per kilojoule or per gram of food than did the other test foods. In contrast, pasta, oatmeal porridge, and All-Bran cereal produced relatively low insulin responses, despite their high carbohydrate contents. Carbohydrate was quantitatively the major macronutrient for most foods. Thus, it is not surprising that we observed a strong correlation between GSs and ISs (r = 0.70, P < 0.001). However, some protein and fat-rich foods (eggs, beef, fish, lentils, cheese, cake, and doughnuts) induced as much insulin secretion as did some carbohydrate-rich foods (eg, beef was equal to brown rice and fish was equal to grain bread).

Mark Sisson had an article about this last year: http://www.marksdailyapple.com/insulin-index/#axzz2SKf8MqnJ
This sums it up pretty well:
"The insulin helps drive amino acids into the muscle cells where they???re needed. At the heart of this process, one thing is for certain: the body knows what it???s doing.
But there???s another dimension to the protein-insulin issue. When we eat protein-rich food, another chemical is released by the body that actually has a contrary effect to insulin. Protein-rich foods also result in a release of glucagon. (Carb-rich food does not.) Glucagon raises blood sugar levels in part to allow for absorption of amino acids in the liver and their subsequent transformation there to glucose. In our evolution, we developed the capacity to make what we required out of what was available. If dinner was going to be part of a mammoth carcass, then the body could enjoy the protein it needed and use insulin response to store essential amino acids. Simultaneously, it had the glucagon to keep blood sugar stable in the absence of carb-based foods."
