Boy am I in the same boat! My amazing eater hit 12 months, and everything went downhill. Now, at 14 months, he's the king of throwing food and eating almost nothing!
The stuff that works for us:
-Drinkable yogurt or kefir once a day (lots of calcium and protein, extra calories, and tastes very good!)
-Fresh smoothies- we make ours with frozen strawberries, banana, OJ, plain yogurt, and any other fruit we have around
-cottage cheese (with or without berries)
-cheese sticks and cubes
-cut up pieces of hot dog (you can get organic, nitrate-free at Whole Foods or Trader Joe's), with ketchup.
-toast with butter and jelly
-canned green beans (Gross, right? But it's the only green vegetable he'll eat!)
-sweet potato fries
-Baby mum mums (or another cracker) with hummos on top
-Earth's Best Oatmeal (Lots of vitamins and iron added!)
-Earth's Best Cereal Bars (ditto!)
-Fruit- tons of this! My son would eat only fruit, if he had the choice. So he eats fresh fruit (berries, melon, oranges, pears, bananas, etc), as well as freeze-dried and fruit leather.
-Annie's Mac-n-Cheese, with baby food mixed in (carrots or squash)
No recipes, sorry. We just keep offering other foods, but only a little bit at a time. We've taught him to put his food in a bowl, when he's "all done" so he doesn't throw it all over the floor and room! We try to never make a big deal about him not eating something, and we just give tiny portions now. I'll offer him one piece of a hot dog, and tell him "That's all you get! You don't want any more, right?" Then I'll walk away with the plate, and he'll point and yell for more. So I'll give him one more piece, and repeat the whole thing. He'll eat a whole hot dog this way, rather than take one bite and throw it on the floor.
So that's the big plan at our house. Like you, we're just trying to get him to eat! :)
