No big deal. Her tastes will change and she will want to try other things. So until then, well, peanut butter is a protein, jelly is a fruit, so get the low sugar/more fruit types. My granddaughter does not like bread much either,, so she opts for a lightly toasted waffle,( frozen foods section) with p butter, strawberry jelly and sliced bananas. Or when you make pancakes, save the leftovers in a sandwich bag and let her eat that, rolled up with p butter, jelly and fruit of choice. ( microwave the pancake to warm it up some) Really,, its no big deal,,, lol kids are funny that way. They may only want pasta with no sauce for a few months, and then the next few months they want scrambled eggs with cheese. Ok,,, so theres a thought. A pancake, served wrap style with scrambled egg and cheese in it. Even a little spritz of syrup. If you get her involved with the "making and choosing" process, you will not have major issues. When my kids were little, I kept small plastic containers of sliced friuts and veggies in the fridge on lower shelves for them to "create-a-snack" This, along with slices of luncheon meat, cheeses, and crackers were very popular with them. Try whole wheat or veggie crackers , served on a plate with cottage cheese, fruit, and veggie slices. DO NOT stress. This is a fun age, Enjoy it. ( If you are really worried, make sure she eats her vitamins) Also it may be the white bread she is objecting to, the texture of white bread can be at best, sometimes " mushy" , try rye or pumpernickel, they are fascinated with different breads like a rye-pumpernickle swirl, or even cinnamon/raisin bread. ( also great with peanut butter and jelly, or apple butter) Hope this helps!
