Honestly, I'm really lucky in the food department. My host family cooks really well, and they give me fresh mangoes in during mango season, roasted corn now that the harvest is coming in, and lately they've been adding beans to the leaf sauce we have for dinner. When I come in to town I can pick up oatmeal, raisins, and snacks, and buy refrigerated yogurt and juice, and in the market there are bananas and cabbages and things like that. I also spend my fair share of time waxing nostalgic about things that are unavailable here, things like these:
1. Breakfast. Specifically whole wheat toast. And juice. And fruit. I'd say coffee but thanks to my American family I get to have Peet's coffee pretty regularly.
Popsicles. Cold things in general, but really popsicles.
Sprinkles. I love sprinkles, particularly rainbow sprinkles. So much that I'm willing to count them as a "food" that I miss.
Cookie bowls. I've never actually had one but I bet it would be good with something frozen and rainbow sprinkles. (But no almond flavoring. I do not miss that. Ever.)
Vegetables. Ohhhhh vegetables. Peanut sauce is great but I wish it came with fresh vegetables.
