Quick and Nutritious Snacks for Various Dietary Preferences

I'd like to explore healthy snack options that cater to different dietary needs. For this request, I'll assume a moderate time constraint of 30 minutes for preparation and focus on the following dietary preferences: vegetarian, gluten-free, and options suitable for individuals with dairy allergies or intolerances.

Could you provide at least 10 healthy snack ideas that meet these criteria? Please include simple recipes or preparation methods and highlight the nutritional benefits of each snack. Consider incorporating a variety of textures, flavors, and ingredients to ensure the options are engaging and satisfying.

Specifically, I'm looking for snacks that are:

1. Vegetarian (exclude meat, fish, and poultry)

2. Gluten-free (use gluten-free flours, grains, and ingredients)

3. Suitable for individuals with dairy allergies or intolerances (offer dairy-free alternatives or substitutions)

4. Prepared within 30 minutes or less

5. Rich in nutrients, fiber, and healthy fats

Some examples of healthy snacks that might fit these criteria include fruit and nut combinations, energy balls, trail mix, and vegetable-based snacks with hummus or guacamole dips. Please provide a range of options that cater to these dietary preferences and time constraints, along with their corresponding recipes or preparation methods.
