J., you're already doing a good job -- variety of foods, variety of serving "styles," etc. -- except for maybe that "force-feeding one bite at a time" thing.
I know you're ready for him to "get over this pickiness at some point" but that point may be years away. My daughter is seven and at this age I can reason with her about trying new stuff, and she might, but she remains "picky" about anyting she deems "spicy," which is many things. My friend's son who is 13 now will at least taste most anything but does not sit down and chow on the international foods his mom loves.
At age two, your son is getting used to new textures and flavors and little kids, as I'm sure you've heard, are really sensitive to food textures, which you can't change or beg or bribe away. Also, I recently saw a news account that said that scientists now think humans instinctively reject new foods at around this age as a hard-wired and ancient way to protect themselves from poisoning--not that adult humans are trying to poison them these days, but the human creature is programmed from ancient times to protect itself by being very selective about its eating, and this kicks in at the age when today's adults want our kids to "just try this"! So some of the pickiness is just hard-wired and has to be overcome once the child is old enough for his curiosity or our convincing to overcome that instinct.
So keep offering, asking, making a game of tasting new stuff, but if you force it -- and if your husband keeps pushing bites at him -- this will become a power struggle, not a feeding issue. Kids realize very, very early that we adults cannot MAKE them eat and cannot MAKE them use the toilet, which is why feeding issues and potty-training issues are constantly on Mamasource! They can control these things at certain points and they will. Eventually your husband, though he means well, will push the spoon at your son one time too many and your son will realize that clamping his mouth shut means he, your child, can be in charge and get a reaction from the grown-ups too. Even negative reactions are reactions and at this age kids will take either kind.
One last thing: I'd never bribe him if I were you. I know some parents do the "eat this and you get dessert" bribe but our kids are so exposed to cupcakes at every preschool event, sweet snacks at friends houses, etc. that the bribe of sweets (I believe) only builds that sweet tooth. That's just me.
Keep on offering, don't make him too much stuff that you think he might reject so you don't waste food. And don't despair! My daughter just fell in love with asparagus so there will be gradual victories!
