food and coffee are a perfect combination and you should not worry about any loss of identity, ambiance or competing aromas when considering the addition of food items (imo).
and pasta is just as good a choice as anything else although i'm not convinced it's necessarily that much easier to prepare when compared to other options. further, there is an enormous amount of cooked items you can offer without the need of a commercial hood, or any hood for that matter.
i would recommend that you first find which food distributors operate in your area (sysco, united, continental, etc.) - check into both national distributors and small, local distributors. once you have identified a few, contact them and set up a meeting with their salesperson. national food distributors carry extensive lines of quality, heat-and-serve products including lines which are organic and/or presevative-free. the prepared food business has changed radically in the last 5-10 years and there are many absolutely fantastic products available.
as far as equipment is concerned, i would highly recommend a flashbake oven (assuming you don't have a commercial kitchen and/or don't want to hassle with one). the flashbakes are fantastic and can cook pizzas in less than 5 minutes. what you can prepare with these flasbakes, in less time than with a microwave, is limited only by your imagination. not only do they cook quicker than microwaves, but they also brown like an oven. hobart, amana and vulcan make the best units - no hood required.
other commercial cooking equipment that i can highly recommend which don't require hoods include highly efficient induction ranges (can't recommend these enough!) and air-fryers which cook "deep-fried" items with air.
i offer a full menu (lunch and dinner) as well as roast my own coffee - customers attracted by the smell of fresh roasted coffee come in to purchase coffee by the pound and/or espresso drinks only to also discover a full menu. consequently, more than often, they decide to stay and eat or return for a meal. those that come in for a meal can't help but be allured by the fresh coffee and end up purchasing a pound or finishing their meals with a specialty coffee drink. it works out beautifully!
