Welcome to DC, Simon85. Can your gf eat rice? I am thinking of rice-based dishes that have lots of fresh green veggies added--sauteed pea pods, zucchini, carrot (or would the sweetness be too much?), eggs. Can she eat green onions? Cilantro? Oregano? Mint? Ginger? Sweet potatoes?
I love this dish made with quinoa instead of the bulgar wheat. You can leave out the cumin if that is too spicy, substitute cinnamon. I have made this with carrots instead of sweet potato. I have also made it with winter squash or pumpkin instead of the sweet potato.
You can add fresh green peas, use veggie stock, leave out the lemon or lime juice, and use fresh coriander, mint, and cinnamon for the seasonings.
Can she eat ginger? A ginger-carrot soup mint be nice.
What about fish/seafood?
