One thing I can immediately think of is avocados - they are both high in fat and carbohydrate, though 80%+ of those carbs are fibrous. One way I've managed to make dieting more sustainable (which is the most important part, making sure you find a healthy diet you can stick to in the long run) are cheat days/meals. This allows you to program in "tasty" meals without the psychological guilt and adverse health affects from these typically unhealthy treats. Most nutritionists will agree that if you adhere to your diet 90% of the time, you're going to be successful. That means in a typical 3 meal/day diet, you've got roughly 2 meals / week where you can cheat and eat whatever without it affecting your health or body composition. My approach, which has allowed me to increase my strength without increasing my body weight, has been through a cyclical ketogenic diet. As always, YMMV, but I have determined through my own empirical research that I am not well carb-adapted, and staying low carb (<50g net carbs) all week doesn't negatively affect my energy levels or strength, in fact it improves moreso than when I ate carbs after workouts. Nonetheless, I love me some carb-rich foods, so once a week, after my biggest workout of the week, I eat roughly 400+g of carbs to refuel glycogen, satiate my desire for a "tasty meal" and overall reward myself for adhering 90%+ to my diet for the week. What's important here is that you plan for the cheat, and that allows you to still enjoy life and food without it negatively affecting your health and body composition.
