Advice for gestational diabetes


I'm a picky eater I don't like allot of veggies and if things don't taste good I won't eat it? Lol. So any advice on food prep that doesn't use oven ( ours is out rn) I feel super upset I failed my 3 hour test. Im feeling super defeated and wanting to cry. We aren't the wealthiest family so its hard to get the really good stuff. So any advice will help. I've already started eating a few things healthy for gestational diabetes tried a few new things out. I still need some help with things I can eat and make that doesn't cost allot and is tasty.
