My son is almost 15 months too. Here is what he eats:
Breakfast: cereal, fruit, and milk
Cereal: baby or regular oatmeal, toddler cereal, whole wheat cheerios
Fruit: Applesouce, bananna
Lunch: grilled sandwhich with cheese, canadian bakon and tomato, with milk and fruit or fruit smoothie (blend forzen fruit with milk and a touch of maple syrup or honey) or scamblled egg with cheese and toast.
Dinner: whatever we eat: vegetable, meat , starch and fruit
For the vegetable dish, he loves carrots or sweet potatos just plain boiled or baked. In general, a bit of onion and garlic will make him eat anything.
Meat: not really a bit meat eater, but loves sausage, salmon, catfish, meatballs.
Starch: potato (baked or mashed or fried with onions), brown rice in peanut saouce, whole wheet pasta with pesto, cous-cous.
Snacks: cheerios, tricuts with cheese, fruit, rasins, yogurt, hummus, penut butter, cereal bar, granola.
Hope that gives you some ideas. Let me know if you need recipes for any of the things.
