As an alternative to clip-in pedals a platform like this works well
MKS GR-9 Platform Pedals, Silver | Amazon.com: Outdoor Recreation It has two screw holes in the front of the pedal where you can install plastic strapless toe clips like this:

If you have large feet a big platform BMX-style pedal with pins like this works well:

Some of these pedals have older-style pins with sharp threads that will cut your skin but the ones I linked to have the newer more friendly style pins.
A basic pedal like this isn't bad:

Clip-in pedals are worth using if you have any inclination to try them. You disengage them by pivoting your ankle outwards. Initially they might seem frightening but are actually pretty intuitive and easy to use. These basic Shimano pedals are good:
Amazon.com : Shimano PD-M520L MTB Sport Pedals with Cleats : Bike Pedals : Sports & Outdoors Hard-soled basic MTB shoes with three velcro straps by any manufacturer will work with them. Attach the cleats about halfway in their adjustment track so the ball of your foot sits adjacent to or slightly in front of the pedal spindle axis.
I use BMX platforms on the bike I use to ride with my dogs so if they encounter trouble I can drop the bike and run to their assistance. It's nice to have at least one bike with platform pedals you can ride with whatever shoes you've got on. Clip-in pedals and dedicated shoes are better for efficiency and comfort on longer rides.
edit: Just noticed these pedals which appear to be rebranded Wellgo MG-1 with new-style pins. If these really are MG-1s this is a very good deal:
