You can serve BLTs for dinner any time of year, but they're especially good in summer when tomatoes are at their best.
See the blog post above for suggestions of what to serve with BLTs.
Add other ingredients to the sandwiches if you want, like avocado, sprouts, arugula, cheese, pickled jalapenos, red onion, etc..
Any type of sliced bread can be used for BLTs. Sourdough and white bread are popular choices. Whole wheat bread is delicious too.
