My daughter is 17 months old and has always eaten the same foods that I prepare for my husband and I (with some modifications like no condiments, and less salt and fats if it's easy to separate a portion for her from the main meal).
On occasion she will turn up her nose at something that she previously devoured so I know she likes it. I've found that if I just change how I serve it can make the difference in whether or not she eats it.
For example, if she doesn't want to eat something I put on a plate, like veggie stir fry with whole wheat rotini noodles which is usually a favorite, sometimes I can switch it over to her Snack Trap brand snack cup. These are great because the lid lets her stick her hand through to get the food but minimizes spills. I don't know why the bowl makes a difference when it's the same food, but sometimes it does.
If it's not a food that's finger friendly, like soup or casserole, I have found that on those occasions I can entice her to eat by using a slice of bread (luckily she likes whole grain, natural bread) or cheese as a "spoon" to scoop up bites of the unfavored food. So far it has worked every time and she has eaten everything that she wouldn't eat off a regular spoon.
You could also try using fruit slices as "spoons". Some of the combos my daughter likes are apples dipped in peanut butter or banannas dipped in yogurt.
I've also wrapped avocado slices with lettuce and lunchmeat, and veggies in cheese.
One other tip that's worked for me...If my daughter doesn't dig in I'll sit with her and let her feed me. She thinks it's great fun because I really hype up how much I love every bite. It doesn't take long before she thinks she's missing out, and when I tell her no thank you and that she should eat it she usually mimics my enthusiasm and suddenly desides its something she loves too.
Good Luck, and continue to offer the same foods that you and your husband are eating.
