Sounds amazing, doesn't it? Curried tuna, carrot and hummus couscous. The mouth waters just thinking about it.

But wait -- there's more. This healthy recipe's got a couple of sources of lean, complete protein: tuna and hummus. Its overflowing with nutrition from veggies too, like carrots, garlic, red pepper, onions and greens (rocket or arugala). And the health benefits of the turmeric in curry are plentiful.

The fun begins, though, when you start imagining all of the ingenious substitutions you could make to boost the nutrition and healthfulness of this recipe. Join me after the jump for some specifics.

• Since couscous isn't really a whole grain, you could use brown rice, quinoa or spelt berries.
• You may not love canned tuna, and you also may be concerned about mercury, so try another fish, like wild Alaskan salmon, or a vegetarian choice like tempeh.
• Change up the veggies, just for fun.
