Well I have CF related diabetes so I'll just list off the normal stuff I eat. <img src="i/expressions/face-icon-small-smile.gif" border="0"> All of this is low in sugar and medium to high calories.
Snacks: beef jerky, nuts (peanuts, cashews), olives, cheese, deli meats (salami, pepperoni, ham etc), guacamole, cheese dip with tortilla chips, potato chips, nutella or other spreads on crackers
Meals: Hamburgers/cheeseburgers, fried or baked chicken, turkey devonshire sandwich (open faced turkey sandwich with tomatoes and bacon on top, covered in cheese.. yum!), steaks with baked potato with sour cream/butter, french fries with cheese or gravy topping, chicken or steak salad with fries on top, bacon sandwiches, fried zucchini, homemade quesedilla with various fillings (lots of cheese, olives, seasonings, chicken), hearty soups/stews (wedding soup for example)
that's just a few ideas, just ask me if you need more. <img src="i/expressions/face-icon-small-smile.gif" border="0"> what kind of stuff were you looking for?
