In the short term, offer the rabbit that same food. Too many changes at once are likely to upset the rabbit and food is one thing you can keep constant (at least for a few days). As the rabbit gets more confident, if its diet is not ideal, start to change its food. Rabbits are herbivorous and their ideal food is growing grass. Grass provides the correct balance of nutrients and fiber, which grinds down their teeth and gets their gut to work. However, it's not possible to provide good quality growing grass all year round, especially for an indoor rabbit, so a compromise always has to be reached. The best food for your rabbit is growing grass but you will most likely need to supplement the grass with other foods. Fresh green hay is the best alternative to grass. If feeding pellets, only offer small amounts, the rest of the diet should be hay. Just because rabbits are herbivores, doesn't mean that they should be eating any plant-based diet.  Try to avoid muesli type feeds. These are far from ideal, and avoid using if at all possible. A muesli food has identifiable ingredients such as squashed peas, corn, wheat, nuts, and biscuit. The problem is the rabbit will eat the tasty bits and leave the nutritious parts. This leads to weak bones and overgrown teeth, and the rabbits also tend to become overweight. It is an old wives tale that rabbit's under 6 months of age should not get fresh greens and vegetables. The trick is to give in moderation as a daily treat. Small pieces of fruit may be given on occasion, but should be strictly limited due to their high sugar content. All new foods should be introduced slowly over time. If any digestive upset is noticed, offer the rabbit unlimited water, unlimited hay and some old-fashioned (long cooking) oats. Remove all other types of food and restrict the rabbit to this diet for three days. If the digestion has returned to normal, you may reintroduce other foods again slowly, one at a time. Also, any food can potentially cause problems if eaten to excess. Carrots contain a lot...
