Eggs.
Eggs provide a decent amount of iodine, but also not an excessive amount. The thyroid hormones are literally made of iodine. Iodine turnover is high in the first trimester due to increased thyroid hormone production. However, iodine levels can also get too high due to recycling and the breakdown of T4 to T3. Eggs help fill this need without being too high in iodine. Pregnancy increases iodine needs by 50%.
Eggs also provide selenium, which is required for the conversion of T4 to T3, as well as antioxidants needed to reduce oxidative stress and insulin resistance.
Eggs also provide zinc, which helps with insulin storage, as well as the conversion of T4 to T3 with selenium
Studies also show that eggs help balance post-prandial (after-meal) glucose levels. (both high and low)
Eggs are a perfect pregnancy food, providing nearly all of the nutrients needed to grow a baby (it's what they do). Make sure to pair eggs with antioxidant-rich fruits and veggies, as well as foods that supply calcium and other minerals.
Eggs are usually well tolerated in the first-trimester, when other proteins are hard.
If you are averse to eggs in the first trimester, my second pick is beans (lentils, chickpeas, lima beans, black-eyed peas, to be specific)
